He's playing "Power of Love" same song he played with his band at the audition after school in part 1 where the songs writer/preformer Huewy Lewis tells them they're "just too darn loud".

Also the theme song played throughout the movie, I'm sure you noticed it lol

I’ve seen this brought up a few times but I think I have a decently detailed reason.

According to the rules the movie sets he should be able to come back to the same 2015 he left from. In the first movie we see that Marty does not immediately disappear when he interrupts his parents first meeting. He has until the kiss at the dance a week later to set things right because that’s when they fall in love. Similarly young Biff getting the almanac doesn’t immediately change anything, old Biff would not fade away. When Marty is in the alternate 1985 he sees on the montage about Biff’s life that he doesn’t place his first bet until his 21st birthday. So technically Marty had 3 years (assuming Biff is 18) to get the almanac back, unless Biff memorizes it first. But throughout the movie we see young Biff scoff at and ignore the almanac mostly. He never had a chance to memorize any facts from it before Marty takes it back so nothing has changed yet.

When doc explains time travel in the first movie he mentions that Einstein the dog instantly skips over one minute to arrive in the future. He’s not in stasis or something like that, the trip is instant. So if old Biff traveled forward in time from an as yet unchanged past, he would arrive in an unchanged future. Then the ripple effect (which doc also explains) would happen. Now that Biff left the past and things were left to run their course, young Biff places that bet on his 21st birthday and the ripple effect starts changing the future.

Thanks.

Does anyone know where i can find a replica of this keychain?

In one of the original scripts, this issue was addressed, and Marty plays it off like its joke money after the character that becomes Lou notices.

By the final script, it wasn't an issue anymore, and it is just ignored.

But we're here to discuss it, right? OK. Here's your excuses, lol.

#1) How often have you ever taken change and inspected the dates on the coins? So, why would Lou bother, either?

#1a) The coins may not have even been printed after 1955 anyway. It's not uncommon for 30 year old coins to remain in circulation if they're still the current tender. As of today, 2023, you may well just find some of the change you currently have is dated from the 1990s period?!

#1b) Let's say some of the coins did have future dates on them? Don't expect them to all say 1985 on them. For all we know, they say 1956 and no one looked at the coins' date for the next 2 months, and by the time they did, the date was correct, and no one was the wiser.... same reasoning could last for any year up to 1985. Luckily, nobody noticed. 🤷‍♂️

#2) What if it was noticed? Big deal. If you found a coin that said it was from the year 3069, are you going to believe it's a coin from the future or a gag? Personally, I'd think it was counterfeit or part of some board game I've never heard of? Some kid would probably keep it in his collection, and that's the last anyone heard of it till he died and with no backstory and a date on the coin that's now the guys distant past, it made no relevance to the coarse of history.

#2b) Hey, everyone. I just found a coin with a future year on it..... what do you mean it must be a misprint or fake? It's evidence of time travellers comi...DUCKS STOP THROWING THINGS AT ME, IM SERI..OWWWW THAT HURT. ITS EVIDENCE I TELL YOU 😭

Post some of the trivia you know about the BTTF Trilogy and related content.

#BTTF

Doc's name is Emmet L. Brown. If you simplify the spelling, it's EMIT. Spell it backwards, and you have TIME.

The original script did not include the Delorean as a time machine. Instead, it was a refrigerator, and Marty needed Docs help in 1955 to get to a nuclear test site to be sent back to 1985, which became a futuristic utopia with flying cars when Marty returned.

Universal wanted the name of the movie changed to "Men from Pluto" to which Bob Gale and Robert Zemickis sent a letter to Universal saying lol.

Mr. Fusion is a Krups coffee grinder.

It's a well-known fact that when Michael J. Fox wasn't originally available to star in the film, so Eric Stoltz was cast. Filming commenced for a few weeks but wasn't working with Eric, so they begged for their original choice of Fox. However, did you know this also meant the re-casting of Jennifer Parker? Due to height differences, the part fell from Melora Harden to Claudia Welles!

Other actors who were considered for the role of Doc where Jeff Goldblum, Gene Hackman, John Cleese, John Lithgow, Eddie Murphey, Mickey Rourke,

Steve Martin, and The Fonz. Eyyyyy!

Many of the clocks in the beginning of the movie are tribute to past movies about time and time travel.

Einstein is a Catalan Sheepdog.

Robert Zemickis and Bob Gale have stated that no reboot will occur during their lifetime.

John Delorean, the creator of the DMC Delorean automobile, sent a thank you note to the directors for immortalizing his vehicle in cinematic history.

The script was first rejected almost 50 times before being given the ok to make.

The idea behind the film was Bob Gale finding his father's year book and wondering if they'd get along at the same ages?

Have you ever noticed on the back of Docs van there's a sticker saying "One nuclear bomb can ruin your day"? A reference to the foreshadowing of the original script.

was the top grossing pic of 1985.

Johnny Depp auditioned for the role of Marty. He left such an impression that Bob Gale does not recall any of it!

Doc pronounces the word "Jiggawatts". It should be "Gigawatts", as in "Gigabytes".

When Tom Wilson is asked about this movie by enthusiastic fans, he will often hand them a postcard of frequently asked questions as a timesaver.... or play them a song.

Marty McFly mimics famous rock stars during the later part of his performance at the school dance, when he starts playing heavy metal. His kicking of speakers (The Who), full circle guitar strum (Pete Townshend of The Who/Bruce Springsteen) playing the guitar while lying down (Angus Young of AC/DC), hopping across the stage with one leg kicked up (Chuck Berry/Young) and his solo (Jimi Hendrix/Edward Van Halen).

Very true.

The guitar is made by Gibson and is the model ES-345. which was released by Gibson in 1959! That's 4 years after Marty is seen using one at the Enchantment Under The Sea Dance!

So, how can this be?

Well, the obvious answer is, it was an oversight by the filmakers wanting Marty to use the same guitar famously played by rock 'n roll legend Chuck Berry... whom penned the song Johnny B. Good in 1959!!. (The same year the guitar was released!)

So, how can we explain this one?

OK, here's how lol.

The guitar was first released in 1959, however, that doesn't mean it was first built in 1959. It could well have been an early prototype that ended up in the hands of Marvin Berry somehow? Perhaps he was someone testing out the guitar for Gibson to see if it was worth manufacturing copies for retail sale?

Or, perhaps Marvin Berry created the guitar, or knew the creator, and Gibson eventually saw and heard it and decided to buy the design of it for retail? Yes, it does clearly have a Gibson logo already on it, however it's not unthinkable to be an authentic Gibson neck from another guitar that's been used, or if it's a modified and custom job of a pre-existing guitar?

Afterall, Marvin was definitely ahead of his time having a guitar amplifier that could produce distortion and reverb sounds that would not be commercially available for give or take another 10 to 15 years? For all we know, Marvin Berry could very well have been as great of a musical tinkering inventor as Doc Brown is to time travel inventions!?

Yes. But also no. Lol. The town square with the clock tower was shot on the Universal Backlot located at Universal Studios in California.

It was constructed long before Back to the Future and is still used to this day. You can actually visit the area on Universal backlot tours and see for yourself it's a constructed area that's not real buildings and can easily be modified into whatever is required of it, such as Hill Valley Courthouse in 1955, 1985 or 2015, or perhaps Hazzard County in the Dukes of Hazzard TV show, or Kingston Falls (Gremlins) and many 100s of other movies and TV shows since its construction in 1948.

Universals official page for the backlot the particular location is called Courthouse Sqaure.

Footage example of the tour.

Wikipedia info includes list of movies and television it has appeared in.

For many reasons.

1. They'd already planned the train robbery and where to place the Delorean etc.

2. Carting around a Delorean is going to attract a lot of attention anyway. Even covered. Plus, it would slow them down and be easy to be hunted down and shot like ducks.

3. It's 1885. It's not like the next nearest town is close by, and it would be an obvious place to be hiding and found.

4. The heat of the desert and requirements for food and water would be too hard to cart enough around, and they wouldn't risk hiding out in the mine the Delorean is buried in.

5. Docs plan requires his shop to prepare the Delorean.

6. Its the old West. Even if they camped out, there's still plenty of other danger from wild animals, reptiles, gunmen, bandits, American Indian tribes and what not.

7. They'd require making camp and using a fire to stay warm, a dead giveaway when being hunted.

8. Safety in numbers. Better to be in a law abiding town with a Sherrif than the lawless wastelands.

9. The plot would suck.

A: So Lea Thompson could have a role to play! Duhhh.

Lol, nah

It's theorised that McFly men are attracted to certain looks in women that repeat over history. Maybe it skips a generation, as Jennifer doesn't look like her, and we have no idea what Georges mother looks like, or if she was McFly?

A: The lightning struck the flying Delorean hurtling it through the air in a back flip at over 88mph. The fire trails are not 9's or 6's, they are curls. The car basically flipped back in the air, like a roller coaster in a loop and blasted its way into 1885.

Q: Couldn't Marty just change the date from 1885, to 2015 and get the hover conversation fixed?

A: Firstly, Why? In Docs letter he stated the car would never fly again. So why would Marty even think about it?

Secondly, Marty wasn't gonna risk fucking up going back to 1885. It wasn't even guaranteed he was going to make it to 1885, he had to put his faith into '55 Doc being able to get the time machine to work.

Could Marty have benefited from the schematic diagram they used to fix the Delorean?

A: Being that he was going to 1885, to the man who drew up the instructions, '55 Doc would've kept the schematics to burn after Marty successfully travelled from 1955 to 1985. So they'd logically not still be in the Delorean, just incase something did go wrong. Better to not allow someone to discover a car and have instructions on how to use it.

Could Marty, or anyone else, find the flux capacitor or Mr. Fusion after the train destroyed the Delorean, and reverse engineer it?

A: I'm pretty sure they'd have expected a train to come along and destroy the time machine when it got back to 1985. Marty was just so glad to be back and looking around he forgot to get out asap.

If you think about it, what where Marty and Doc going to do when they arrived back in 1985? There'd be no way to plan having a toe-truck or anything be waiting near by, or have time to go get one, even if Doc still owned one, a train was garunteed to come along and crash into the Delorean before they had a chance to get it off the tracks.

Doc most likely chose the specific time of day to return to, knowing roughly when the diesel train passed through there, giving themselves just enough time to get over the bridge, come to a stop, OR specifically discussed hitting the brakes at that spot Marth did stop just after the crossing, as maybe it was a spot that if the Delorean was smashed to pieces, it wasn't going to attract a hell of a lot of attention.

I dunno. I'm making crap up, but it makes sense it was most likely a calculated spot to rest the Delorean so the train didn't have time to stop and not destroy the vehicle.

Marty does leave the wreck along the railway... it'd take a lot more than salvaging Mr. Fusion to make a time machine. Doc most likely would've probably gone back to the future to check things where OK before going back to 1985 to say bye to Marty. So he knew Marty didn't salvage anything or anyone reverse engineered anything.

$80 doesn't seem that much to pay to save your life, but in 1885 in the USA $80 would be roughly almost $2500 in 2022 as this was written according to this site.

In 1985 it would've been roughly $850 to $900 at the time. Keep in mind, Doc most likely burned whatever cash he had that couldn't have been used in that time period, and used up what he did have to set himself up as a blacksmith to which the money he did have was from blacksmith jobs.

To those of us who where born before 1985.

Do you realise we're now older, and a further away distance in time, than those between 1955 to 1985?!?!?!

The paradox theory refers to unexpectedly running into yourself where the other self has no knowledge of time travel and the events change the future in someway that completly changes the timeline.

In BTTF2, Old Jennifer passed out because she saw her younger self, the timelines had not caught up yet fot old Jenniffer to have any memory yet that shed even time travelled before! It simply shocked her and she passed out. But nothing would really change for her future when she comes to. However, Young Jennifer would see herself as an old lady, and be shocked, but what causes the paradox is multiple possibilities, but let's say for example at that moment she thought she had let herself go, or hated the way she looked, then when she got back to 1985 and resumed her life, she could have started becoming obsessed with fitness and plastic surgery etc and the events that lead to caused a completely altered future for herself, which means she never gets to see her younger self in the future at that point to want to change things, and it starts a chain reaction of different scenarios or time loops that shouldn't be taking place, or leading to a point in time where her existence shits itself and the universe explodes lol. Most likely not, but a possibility in a worse case scenario of events taking place and glitching because things have happened and things have been prevented from happening that conflict with other conflicts and new events.

Jennifer is the only one who Doc theorised would pass out. It's not like meeting yourself has some sort of effect where if the same mollicules are too close, they explode or you pass out.

__________________________________ .

If Doc ran into himself in the future, then both Docs could wave to each other or whatever, but know, it's best not to engage in conversation as any knowledge either way could result in changes, past or present, that could jeopardise their current existences.

Cartoon logic would suggest if future Doc is told by future-future Doc he needs to get a mole fixed, then future Doc fixes it, it could then lead to future-future Docs head changing into an elephant. Lol.

But, the two Docs wouldn't pass out or the universe explodes the moment they meet, it's the changes to time that it can cause, and the chain reaction of events that prevent the current one from even happening that eventually may lead to timelines just going bonkers till it crashes holding up a sign saying "Congratulations, you broke the universe"

What was the meaning of docs experiment at the start of the first film? He seemed pretty excited that the clocks were 25 minutiae slow.

A: Hilldale was always destined to become a crappy neighborhood in both timelines. Before Biff steals the DeLorean, we can observe:

• multiple instances of graffiti in Hilldale
• instances of litter in Hilldale
• the negative dialogue about Hilldale by the policewomen, [mentioning Hilldale is a breeding ground for tranqs [people who abuse tranquilizers), lobos (people with a diminished mental capability, similar to people who have undergone a lobotomy) and zipheads (another negative term for a drug addict, similar to crackhead, cokehead, etc)]
• The cab driver telling Biff “this is a rough neighborhood”
• Marty Senior’s dead-end loser office job where he can’t afford a nicer home
• The McFly home has no modern furniture because it’s all furniture from the late 80s.

These things were put into Hilldale by Gale & Zemeckis to display Hilldale was never a good neighborhood, even before Biff stole the DeLorean.

A lot of people ask if this hard hit had anything to do with MJF getting Parkinson's or lead to a concusion?

The simple answer is no.

The sound you hear in the film is just that, a sound. In most major motion pictures the films use what's known as a Foley Artist. These people record sounds for films. What you hear as Marty's head hitting the pavement is not the actual sound produced as MJF did that scene. It was most likely a Foley Artist probably recording themselves punching a chunk of meat or something?

Not all sounds are recorded from the actual action either... such as the sound of the pouring rain in part 3 was not actually the sound of water, but instead sizzling bacon!

For more on Foley Artists, use Google you lazy bastards. 🙃

In the alternate 1985 from part 2, do Doc and Marty still know each other?

When Marty and 1955 Doc discover 1885 Doc's grave and newspaper articles, that gets Marty to go back to 1885. Also, as the gravestone implies, Clara is still alive on 7th Sept.

But, when Marty goes to 1885, he influences Doc's actions and leads to Doc saving Clara from falling into the ravine.

But, this means that in proper 1885, when only Doc was there without Marty, Clara died by falling into the ravine, presumably on 3rd Sept, which means she couldn't have erected the gravestone. But this could still be explained as maybe in 1955 before Marty went into the past, the ravine name had already changed to Shonash instead of Clayton (as Marty's memories are from his 1985 pre-time travel days)

Then, as Marty and Doc leave 1885, they destroy the tombstone and change the past - wouldn't this create a paradox? As then the precipitating event of 1955 wasn't possible, so Marty would never have gone back to 1885 in the first place?

In the first movie, the precipitating incident is kept as is; Marty sees Doc die in the end and accidentally still travels back to 1955. In the second, the precipitating event is Doc coming back from the future to take Marty and Jennifer to 2015 - which is also kept intact, but in the third movie, the precipitating incident is tampered with.

The cars internal combustion engine runs on gasoline. The time circuits are first powered by plutonium and then Mr. Fusion.

This is not something part 3 made up for plot deductions. It was always running on Gas/Petrol.

When Doc says it required something with a little more kick, he is reffering to the time circuits Marty is asking about. Not Marty asking if the car itself has some brand new invention of an electric engine or whatever... Marty already knows how a cars engine works and what fuels it, so why would he ask a stupid question like that? He was reffering to the time circuits.

Further proof is trying to get the car to start. That sound you hear is a fuel injected combustible car engine. Electric motors wouldn't make any noise, let alone the sounds it does make.

Plus it's also a theory gasoline may blow out the exhaust pipe fast while going through temporal displacement hence why the car leaves fire trails behind and why Marty ran out of gas so fast when he got to 55?

Theories are just theories. They don't need answers as they're up to you to beleive or dismiss because no evidence supports them. Also let's keep these theories tied into the movie, not those wild ones like Doc is actually Doctor Who 🙄

#DOC IS SUICIDAL It's theorized that Doc risked his entire family fortune on the time machine so much that he is willing to kill himself if his calculations are not correct, and willing to take Marty down with him which is why he drags Marty back into the line of the Delorean as it speeds towards them during temporal displacement number one.

#MARTY CAUSED THE BRUISE ON 1955 DOC'S HEAD Doc explains it was November 5th 1955 when he came up with the idea for the Flux Capacitor after trying to hang a clock by standing on the edge of his toilet and slipped off hitting his head, and when he gained consciousness he had the idea for the Flux.

It's theorized he slipped due to being startled by Marty calling Doc from Lou's Cafe and caused Doc to slip and fall... another theory is Doc didn't answer because he had already slipped and fallen and was unconscious.

More likely reason is Docs workshop is the garage and doesn't have a phone line there, but he may well have been unconscious at the time too.

#NOBODY CALLS ME CHICKEN Marty's peeve about being called a chicken isn't shown until part II. It's theorized something has changed since Marty interfering with the events of his parents in 1955 that he has come to never let anyone call him scared.

It is possible, but then again, no events in part one show this characteristic trait is not already present and just wasn't triggered during the events of part 1.

When old Biff went back to 1955 to give the sports almanac to his younger self, shouldn't this have caused him to go back to the alternate 2015, the one stemming off of 1985?

I just looked up as I am writing this, apparently he changed history so bad that he didn't exist in 2015 anymore as he would have died earlier. Does this mean the Delorean that old Biff took just magically reappeared back in the same spot as if he never took it? And no-one except Marty and doc would actually know old Biff ever existed ?

In the comic series he takes a few years to build the time train and eventually completes it mostly except for the components needed to make it travel in time and fly etc.

He created a small cart time machine he manages to roll down a hill hurtling him into the future beyond 2015 where he has a lab and takes parts back in time to complete the train. He doesn't really explain how the tech works, but it runs on steam, and could possibly be a one way trip. He takes that risk.
