Back to the Future Part II

Continuity mistake: At the end of BTTF 1, when Doc tells Marty and Jennifer that they have to come back with him to 2015, while they are sitting in the DeLorean, the Doc says," ...where we're going we don't need (pause) roads," and as he says "roads" he puts his silver glasses on normally. But in the beginning of BTTF 2 in the same scene, when he says," ...where we're going we don't need (pause) roads, he swings his glasses on really fast with only one swish as he says "roads."

Continuity mistake: When Marty is reading the letter from the Western Union man, he's standing with the letter in front of him at chest level. Switch to side camera angle and he is now bent over, holding the letter down to the car's headlight. Switch angle again and he's standing up again, with the letter back in front of him.

Continuity mistake: When Marty's on the hover board on the lake, watch the Clock tower's entrance behind him: Depending on if it's a wide, medium or side shot, the number of guards change from one to two, or one that runs away but suddenly appears back in place.

Continuity mistake: When Doc, Marty and Jennifer have arrived in 2015 Doc tells them that the time of the day is 4:29 pm. However the destination time still shown on the time circuits' display from their time travel to the future tells us that they should have arrived at 4:29 am.

Continuity mistake: When Marty is playing his song on stage (during the part where he knocks over the speaker) the music playing is at a different stage to what it was in the first film. The music is now a few seconds ahead.

Continuity mistake: We see Marty putting on his right Nike boot but not his left. The camera cuts from his feet to his face saying "power laces, all right" then back to his feet, now both boots are on. (00:07:45)

Continuity mistake: At the end of BTTF, when Doc drives up to Marty's driveway and tells Marty and Jennifer to get in the car to go to the future, Marty asks Doc, 'Why, what happens? Do we become a**holes or something?' Then Doc replies straight away 'No, you and Jennifer turn out fine, it's your kids, something's gotta be done about your kids.' At the start of BTTF2 when the same scene is played again, Marty asks the same question but this time Doc pauses before he replies to Marty's question. (00:02:00)

Continuity mistake: At the end of the first film when Marty leaves the garage to greet Jennifer, he does not have a watch on throughout the whole scene. In the identical scene at the beginning of this film, Marty is wearing a black watch.

Continuity mistake: When Biff and Marty fighting over the almanac while driving towards the tunnel, the almanac flies out of their hands and lands on the front windshield. Biff slowly reaches over the windshield blocking the center rearview mirror entirely with his right shoulder. Cut camera angle and the mirror is unblocked, showing Marty to the rear of the car, then a reaction shot of Biff seeing Marty in the mirror, all while he is still blocking the mirror with his shoulder.

Continuity mistake: At the beginning, when Marty is examining his truck in the garage, the left side of his shirt is tucked-in in the front, but in the first film, Marty's left shirt tail was hanging out.

Continuity mistake: Marty's hairstyle is different in the starting scene in BTTF2 to what it was in the scene at the end of BTTF (It is flatter).

Continuity mistake: When Marty gets locked in Biff's garage, we see that he can't push through the two garage doors because there's a lock on the other side. Yet, when Biff comes out to go to the Prom dance, he opens them in literally no time at all with no resistance. We don't even hear him unlock them.

Visible crew/equipment: Just as Griff is about to crash through the front door of the court house after he is chasing Marty on the hover board, you can see someone (the director?) on some sort of crane in the reflection of the glass. (00:20:58)


Continuity mistake: When Old Biff is seen watching the hover board chase all the monitors on the wall in the Cafe 80's are turned off even though they were all on two shots prior.

Continuity mistake: When Griff pulls "Gramps" Biff out of the cafe 80's, as he swings back into the cafe notice that he swings around twice. (00:15:00)

Continuity mistake: When Biff is trying to run down Marty on the hoverboard, as he comes out of the tunnel there is a shot of the manure truck driving down the road. Cut camera angle to Biff missing Marty and hitting the truck, which is now at a dead stop, however there was not adequate time to do this and appears that the truck was driving then instantly stopped.

Continuity mistake: The small black pickup Marty is given at the start of this film is significantly different from the one he's given at the end of the first movie. Yet the moment is supposed to be the same one.


Continuity mistake: In the first film (1985) when Marty opens the garage and sees the black Toyota pick up truck, we see instruments on the wall. In this film, they are different.

Continuity mistake: When Marty is waiting for Griff he orders a Pepsi and has trouble opening it, but at another angle it's out of his hands and on the table, then in the next shot he's trying to open it again. (00:13:41)

Plot hole: After Biff steals the DeLorean and travels back to 1955 with the Sports Almanac the movie states that he creates an alternate timeline. Doc Brown does a good job of illustrating this on a chalkboard. So if, as Doc Brown states, Biff created an alternate timeline, then when he travels back to 2015 it would be the alternate 2015. Even if the original timeline stays intact with Doc and Marty in it, they'd be trapped there because Biff took the Delorean and returned it to the new timeline, not the one they're in.

Suggested correction: When Doc explains to Marty the events that changed the timeline from 1955 onwards, several hours have passed since they returned from the (original) 2015. Old Biff likely returned to the original 2015 not long after after giving young Biff the almanac, so it is entirely plausible that not enough time had passed for the alternate version of 2015 to take ahold. When Doc tells Marty if they were to go back to the future they would be going to an alternate future, enough time had passed for the future to turn into the alternate future.
