Back to the Future Part II

Question: When Marty and Doc arrive in the bad 1985, they learn that 1985 has changed and are told that alternate versions of themselves exist. Alternate Doc has been committed and alternate Marty is at a boarding school in Switzerland. Nice movie trick to keep them from running into their alternate selves. Question though, isn't the 1985 at the start of this movie also an alternate 1985? This too has been altered from the original 1985 as seen at the beginning of the first movie. So, where are the alternate Marty and Doc in the timeline when Marty's family is actually upper middle class? Since this is an alternate 1985 as well, where is "rich" Marty? Why didn't he bump into his other self, the Marty that owns the black pickup truck?

Carl Missouri

Chosen answer: We see the alternate Marty depart for the past at the end of the the first movie. As for Doc, as he's simply lived through the thirty years from when the timeline was changed, rather than jumping through time to get there, he actually is the alternate Doc.

Question: In the scene where old Marty enters his house and pushes a button, a computer voice says, 'lithium mode on'. What does that mean?

Answer: Lithium is used to treat bipolar disease and other mental problems. So 'lithium mode' probably has a calming effect when you're depressed or stressed or whatever.

Question: Why was old Biff seemingly in agony when he returned to 2015 after stealing the almanac? Did this have to do with this not being his future anymore?

Answer: There is a cut scene of old Biff disappearing after returning the DeLorean.

Answer: I saw a behind-the-scenes special about this, and it said the intention was that after giving the book to himself (thereby changing his future) something then happened to Biff after 1985 but before 2015- possibly being killed by Lorraine while they were married. This is why, after changing his past, Biff shouldn't exist in 2015. This incident was never scripted or shot, but that was the idea. Something similar happened to Marty in the first movie. As he faded from existence, he became sick and weak.

Question: In the shot when Doc is in the time machine and it is hit by lightning, it apparently explodes. After the initial explosion you can see what appears to be two backward nines. Does anyone know what this means?

Answer: Whenever the Delorean travelled backwards or forwards in time, it would leave a trail of flames. There was no reason given, but it was a neat effect. When it was struck by the lightning it activated the flux capacitor, etc. And sent Doc and the car back to Jan 1st 1885. The "double nines" you saw was because the Delorean tilted on its axis.

Question: When Doc is writing on the chalkboard he says the alternate 1985 is alternate to him, Marty, and Einstein, but reality to everyone else. What about Jennifer? Wouldn't it be alternate to her as well? That probably wasn't even her porch they left her on.

Carl Missouri

Answer: Yes, if she had woken up before they fixed everything, she would have been in the same position as Marty and Doc. In the heat of the moment, Doc just neglects to mention Jennifer...although Marty does ask about her just before they travel back to 1955, Doc insists that when they fix the past and re-establish the original 1985 timeline, it will transform around her and when she wakes up she won't notice anything amiss.

Answer: As response to the porch, that was the only known house to Marty that Jennifer lived at. If it was no longer her house, the people living there may not have looked outside to see her there. However, odds are that the same family lived there (as probably most cases there). Remember, the only reason for the different family living in Marty's house is because of the connection to Biff (he married Lorraine and shot George) so that house would have a different owner.

Question: How does Biff know how to work the time machine? Why doesn't Doc notice the date on the machine where it shows you where you have been and where you are going to travel to? Why didn't Doc notice the top of old Biff's cane when he first got into the car?

Answer: He would have noticed the huge display in the middle as well as the numbered buttons, it wouldn't take a genius to figure out how to use it. It seems that Doc also labelled everything which would make Biff's job a little easier. When he witnessed the DeLorean flying in 1985, he would have seen Doc accelerate up to a high speed before disappearing (plus, Biff being Biff he'd probably wanna thrash the **** out of it anyway). In regards to the time readouts, they keep flashing and Doc has to hit them to get them to start working right. He says "Damn, gotta fix that thing" so even if he did notice it, he would mostly likely assume it is part of the same fault. In regards to the top of Biff's cane, they were in a really big hurry to get Jennifer back to 1985 before she woke up. We all forget to do things or miss things when we are in a hurry so he probably just didn't see it. You could also argue that he did see it but just thought it was some sort of souvenir that Marty had brought back.

Question: In Biff's casino Marty is escaping Biff and his goons - he goes into the stairwell and jumps from one stair to another. What I don't understand is how this stairwell works as it seems to be double, with 2 sets of stairs ending up on the same floor parallel to each other, one on one end and one at another but on the same floor. Does this even make sense? Can anyone tell me why a big building would have 2 sets of stairs in 1 stairwell going parallel and end up on the same floors? Any special name for this type of stairwell perhaps? I can't find anything on it.

lionhead

Chosen answer: Your assumption is pretty much correct. There are 2 staircases spiralling around each other like a double helix. It is a fairly common way of constructing fire evacuation staircases as it allows a greater number of people to use them at the same time.

I see, so it's purely for fire escape reasons or more to handle overflow capacity in general?

Question: When BTTF Part II was originally released in theaters, was the trailer for Part III part of the original released film, or was the trailer added in later when it was released on VHS like they did with "The be continued..." when Part I was released on VHS?

Answer: It was part of the original theatrical release, because production of Part III was already finished, and the final film was released only six months after Part II. The trailer was included to give audiences a teaser and keep their interest piqued.

Question: Does anyone know why Marty takes a book of matches off of Biff's desk when Biff isn't looking? I know that the matches come in handy at the end of the film when he burns the sports almanac, but what was his original reason for swiping the matches? Unless he knew beforehand that he was going to have to burn the almanac.

Answer: It seemed more like a reflex action than a deliberate decision. Marty saw Biff's name on the matchbook cover, causing him to pick it up for a closer look, then just stuffed it into his pocket. As you pointed out, they came in handy later. That and when they changed the timeline in 1955 after burning the alamanac, it would also change back to "Biffs Auto Detailing." Gotta make sure you cover your bases when dealing with the future, make sure that everything changes back to normal.

Question: In the scene where Marty's recently purchased sports almanac drops out of its plastic bag, Doc says that he did not invent the time machine for financial gain. In Back to the Future's first Twin Pines Mall scene, Doc says that he'll get to see who wins the next 25 World Series. Can we assume Doc would not have tried to profit from knowing those results in advance?

Answer: It seems that, yes, we can assume that. Doc's very clear on the dangers of meddling with the timeline - it's fair to say that he's intelligent enough not to risk it.

Tailkinker Premium member

Answer: He never intended on betting on it, he just wanted to see who won the 25th world series.

Question: 1955 Doc doesn't believe there is going to be rain and neither does the weatherman as a matter of fact. Why then do we see everything wet long before the big storm?

Answer: One of the running gags in the BTTF movies is the dependability of weather forecasts. Obviously, in the first movie, the 1955 weather predictions were completely wrong, and it had already showered even before the big storm. In the second movie, weather forecasts of the future had advanced so much that storms were accurately predicted down to the second.

Charles Austin Miller

Question: How is Biff from the future able to use the time-machine? He has to: 1) Turn on the time circuits, 2) Set the time destination, 3) Accelerate to 88 MPH, 4) Know to add matter to Mr. Fusion.

Answer: It isn't overly complicated. Once the time circuits are switched on (something you can probably figure out by fiddling with buttons) there is a big section labelled "destination". Logically you would input the day you want to go to. He could then take off and just start driving fast - he wouldn't need to know it has to be 88mph, but the fact that it's built into a car definitely implies speed is necessary. He lives in the future where Mr Fusion exists, so adding stuff to it would just be logical to him.

Question: How did Marty get by Biff's security downstairs when he confronts him in the hot-tub?

Answer: Doc flies to the roof and drops Marty off. This is why he goes up there. When he reaches the edge, he bangs his fist down in frustration because he expected to find Doc waiting.

Question: Given how dumb Biff is, how in the alternate 1985 when confronted by Marty did he remember his old self in 1955 warning him about Marty and Doc. Especially considering when he got the warning, he seemed to be paying very little attention and just walking off.

Gavin Jackson

Chosen answer: After young Biff won bet after bet after bet, he realized that the old Biff was obviously the real deal. As such, he undoubtedly racked his brain in an attempt to recall every detail he could about his encounter with his older self.

Question: In this movie, we meet Griff, Biff's grandson, but in the previous movie, Biff didn't seem to be any kind of relationship, so where did Griff come from? Is there any sort of explanation to Griff's parentage?

Heather Benton Premium member

Chosen answer: It was never really mentioned in any of the movies whether he is in a relationship with someone. Biff could have very well been, it's just never shown because he is at the McFly house in most of his on-screen time.

Casual Person

Question: Why was Doc sent back to 1885 with the lightning if he was not going at 88 mph?

Answer: According to producer Bob Gale, the lightning that struck the Delorean caused it to spin up to 88 miles per hour. If you have the DVD or Blu-ray, watch all of the deleted scenes with the commentary on.

Question: Where are Dave and Linda McFly in the alternate 1985? They don't seem to live with Biff and Lorraine, and they are too old to be packed off to boarding school (like Marty), so where exactly are they? Biff mentions them when threatening Lorraine into staying so its not like they've been rubbed out like George was.

Answer: It's never stated in the film where they are. Biff makes a reference to having Dave's probation revoked if Lorraine leaves him, so Dave has apparently run into trouble with the law. He does appear in a deleted scene, where he has become an alcoholic and appears to be homeless with little contact with his family, likely because of his dislike of Biff, as he appears pleased to see Marty. No scenes with Linda were filmed, as Wendy Jo Sperber was pregnant at the time of filming, although scriptwriter and producer Bob Gale has stated that, had they included Linda in the alternate 1985 scenes, she would likely have become a prostitute, which would tie into Biff's threat to have her thrown in jail.

Question: When Old Biff arrives back in 2015, after going to 1955 to give his younger self the almanac, he is in pain due to being shot by Lorraine in the alternate past he created, which causes him in turn to fade from existence in 2015. But once Doc and Marty have changed the timeline back to the original 1985 etc, would Old Biff still exist in 2015, or was his fading from existence permanent when it happened?

Answer: He'd have come back into existance. The only reason Marty's fading in the first movie was so critical was because Marty himself was the only one who could fix the timeline. So if he faded before he fixed it he'd have stayed faded because there was no one else who would have been "in the know" to bring him back.

Question: Why does Doc suddenly change his ideas (about time travel and not learning too much of your own future) in Part 2? In Part 1, he was determined not to learn too much about his own future, despite Marty trying to warn him that his life depended on it. But in Part 2, suddenly it's okay to bring Marty to the future and give him enough information to try to change the course of destiny for his son. Also, wouldn't it have just been easier to warn Marty about the accident he was going to have that caused his life to go so wrong to begin with? One would have to think that if Marty becomes successful and lives out an entirely different life, then maybe his son doesn't turn into such a wimp.

unicorngoddess

Chosen answer: Marty's saving his life with the note made him realize that some events are worth tampering with. He wasn't aware that Marty's entire life had taken a wrong turn, he'd just read that his son goes to prison after the robbery and takes action on that one thing.

Captain Defenestrator

Question: Can anyone explain why Crispin Glover was almost completely edited out of this film? True, his character wasn't that important, but even in 2015 (when he was hanging upside down after throwing out his back), his character was played by another actor.

Answer: Crispin Glover is not in the BTTF sequels (except where footage from the first film was recycled). There are some contradictions as to the whys depending on who you talk to (salary dispute, Glover uninterested in reprising the role, Zemeckis uninterested in working with Glover again, etc.).

JC Fernandez

Answer: To be honest Glover didn't like the end of part I because the McFlys were rich and love was a better reward, however he complained about not getting as much money as Christopher Lloyd and the others, even Fox. He then sued Universal for using unlicensed footage of him.

His lawsuit was for violating his right of publicity, not for using footage of him. Prosthetics were applied to Jeffery Weissman using an old mold of Crispin Glover to make Weissman look like Glover.

Continuity mistake: In the beginning when Doc takes Marty and Jennifer to 2015 for the first time, they are descending towards Hill Valley. Doc turns the steering wheel to the left but the car goes right and down. (00:05:53)

Biff: Look, Lorraine, you walk out that door and I won't only cut off you, I'll cut off your kids.
Lorraine: You wouldn't!?
Biff: Oh, wouldn't I? First your daughter, Linda. I'll cancel all her credit cards. She can settle her debts with the bank all by herself. Your idiot son, Dave. I'll get his probation revoked. And as for Marty. Well, maybe you liked to have all three of your kids behind bars just like your brother Joey. One big happy jailbird family.

Trivia: When Doc and Marty arrive back in 1955 to stop the handover of the Almanac, there are 4 versions of the time machine in the area at that time - the one they just arrived in from the alternate 1985, the one Marty arrived in from the original 1985 in the first film, the one Biff arrived in from 2015 in the second film, and the one Doc buried in 1885 in the third film.
