Back to the Future Part II

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: 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: 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.

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: The mechanic tells Biff the price of Biff's car is $300. Does that include the damage Biff caused to the truck he hit if the first film and also the price of the horse manure that had to be hauled away? I know Biff goes into a store across the street for a few seconds so we don't hear part of the argument. Wouldn't Biff have to pay more than $300, or was the $300 just for the car itself?

Answer: Remember that Biff's car was going very slowly and hit side on to the back of a much larger truck. It didn't damage the truck, it only caused the manure to come out.

Answer: The mechanic does mention the horse manure in the dialog of the $300 but truck is not mentioned so it's unknown.

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: 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.

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.

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: 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: 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.

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

Question: In 1955, after Biff gets knocked out by George, there is one man who repeatedly mentions that Biff might have had his wallet stolen. In this movie, we have seen many past, present, and future versions of people. I was just wondering if this man is also seen in 1985 or 2015?

Answer: According to the actor's page on imdb.com, Wesley Mann's appearance as the "CPR kid" is his only role in the entire trilogy. He could be in another time period in an uncredited role, but it's more likely than not that his only appearance is in 1955.

Question: Marty prevents the bad 1985 by burning the sports almanac in 1955. However this alone won't prevent Old Biff from taking the almanac from 2015 to 1955. Indeed it raises the possibility that OB will remember having lost the almanac as a young man and choose to travel back to a date other than 12.11.55 to hand it over. I can think of three possible resolutions to this problem: (1) Marty makes a note of the date and time, then burns the almanac as a 47-year-old before Old Biff gets it; (2) Marty informs the 1950s Doc of what is to happen and he resolves to make the DeLorean more secure and/or not to throw the almanac in the bin; (3) Doc travels to 2015 in the steam locomotive and burns the almanac. Any other ideas?

Answer: I don't think it works like that. Old Biff came from a timeline that no longer exists, wiped out in favour of a timeline where his younger self becomes hugely rich because of the almanac, which is then ultimately replaced with a timeline where Marty wasn't involved in the car crash and he, and his children, are presumably more successful. In this new timeline, Marty and Doc would never have been to 2015 to try to sort out Marty's wayward children, Marty would never have bought the almanac, the old Biff of that timeline would never have learned about the time machine, and so would never have the idea of taking the discarded almanac back to his younger self, much less changing his date of arrival to try to prevent the theft. Doc and Marty have nothing to worry about.

Question: When Marty is exploring 2015, who is the man who talks about the Cubs winning the World Series? He looks like a younger actor wearing 'older' make-up, suggesting that he has played another character somewhere within the trilogy.

Answer: He's an older version of Terry, the auto mechanic who fixed Biff's car in 1955 (and charges him "300 bucks"). Originally the scene with old Terry was longer and made his appearance more relevant, but the scene was trimmed for time.

Madstunts

Question: One thing I never got is why Marty is so shocked that the Cubs won the World Series in 2015. He was then going to say something like "It's just that Miami..." but stops and asks another question. Was it ever said anywhere what he was going to say about Miami? That always perplexed me.

Carl Missouri

Chosen answer: The Cubs aren't exactly known as World Series contenders. Put it down to bad luck, but over 100 years, they only have one World Series championship. The last time they won the Series was in 1908, and the last time they were even IN the Series was in 1945. Being a Cubs fan myself, Marty's reaction isn't that much of a stretch. The Miami reference is because they didn't have a baseball team in 1985, which is all Marty knows of course. Since the movie was made, however, Miami has acquired an MLB team called the Miami Marlins (formerly the Florida Marlins).

Continuity mistake: Notice Marty's hair in the scene when he's playing "Johnny B. Goode." It's quite larger than when he says, some seconds later, "I guess that you're not ready for it yet." That's because when he says that, it's a recycled shot from the original BTTF, whereas most shots showing he's playing the guitar are newly made for BTTF2. However, Marty's hair is considerably longer in the new shots.

Trivia: In an interview, the director stated that hoverboards were real, but they weren't on the market because parents didn't like the idea of floating children. He said this as a joke, but this didn't stop mass hysteria as thousands of kids went from store to store looking for hoverboards.
