Back to the Future

Continuity mistake: After George lays Biff out, Marty pulls the family photo from his pocket. The way he holds it suddenly changes, judging by the position of his index finger as the shots change. (01:23:45)

Continuity mistake: At Twin Pines Mall, when Marty is recording Doc Brown, Marty is raising the video camera to record Doc Brown saying, "No, no, no, this sucker's electrical," but when this piece of film is played back in the Doc's garage in 1955 it appears as if Marty was already recording when the Doc starts speaking. (00:25:15 - 00:50:40)

Continuity mistake: At the beginning of the film, when sending the DeLorean into the future, the wide shot shows the DeLorean heading for Marty and Doc then disappears leaving a trail of fire. Notice the cut as the car park goes from being dry to wet with puddles. (00:20:00)

Continuity mistake: When Marty is at the "Start" line waiting for the alarm clock to ring, he moves up his return time and the engine stalls out. Next we see Marty turning an ignition key with several other keys on a chain like the ones used on ceiling fans with the little balls and a plastic fob with the paper insert that reads 555-1138 Out-A-Time on it. After Marty arrives back In 1985 in town square, he pauses and gets out for a moment. While returning the the car he puts the DeLorean in drive and again the car stalls out. Again we see Marty restarting the DeLorean, we see a different set of keys. The key mysteriously changed in the time travel to an after market type with a thin wire ring on it, no key fob and the other keys are missing. (01:38:43 - 01:42:44)

Continuity mistake: When the Doc is trying to pull the cable to connect it the cable is stuck and when he pulls the cable hard the other connection breaks off. Watch when it breaks off you cn see that after Doc pulled it the cable gave him more length and would surely get Doc's arm to the other cable but when they show the Doc a second after he hasn't moved one bit. (01:39:35)

Revealing mistake: At the end, the DeLorean hits the left dustbin and comes to a halt - you can easily see that it's not Christopher Lloyd driving, it's someone with a much bigger build, wearing an awful white wig. Further, he isn't wearing sunglasses until he gets out of the car. (01:45:55)

Continuity mistake: After Doc accidentally unplugs the cable and is sending Marty back, he unplugs the cable 15 seconds later and it shows Doc, and the clock's hand change. A split second later the clock's hand changes again.

Visible crew/equipment: When Marty is riding past the cafe on his skateboard and all the chicks are waving at him, you can see the reflection of the camera lorry and crew behind him. (00:06:25)

AidanN

Continuity mistake: While being chased by Biff, after Marty knocks down a man and a woman, the man stands up and helps the woman stand up, but a frame later he is rolling on the floor with the woman on top of him.

Audio problem: Lorraine comes to see Marty in Doc's garage in 1955 to ask him if he will go to the dance with her. Just before Lorraine moves to the other side of the car from where she walked in, she begins to say something to Marty. The problem is that her lips don't move when she talks, I guess the right clip ended up on the editing room floor. (01:11:40)

Continuity mistake: George McFly's holding a pen in his right hand, then a cut to a wide shot reveals him not holding a pen as he rests his arm away from his body on the table. Then when the camera cuts back his arm is back in front of him holding the pen. (00:14:10)

Paul Andrews

Continuity mistake: Marty is hitching a ride on the back of a jeep, a wide shot shows him going past and beyond the 'Lou's Aerobic Fitness Center' next to the Texaco garage, there's a cut to his skateboard then back to a medium shot of him going pass the same fitness centre again, this time waving to the people inside. (00:06:00)

Paul Andrews

Revealing mistake: When Doc starts up the DeLorean watch the remote when he says to Marty "not me, the car, the car." The counter is static at 00 but the car is moving. (00:19:40)

Continuity mistake: Cafe 1955, when Marty enters for the first time. The arrangement of the coats on the rack to the right-hand side of the cafe doors changes upon Marty's initial entrance and returning to the counter after using the phone booth. (00:35:50 - 00:36:40)

Continuity mistake: In the cafe, the menu in front of Marty changes after Biff leaves. It starts looking like an ice-cream menu, with swirly lines at the top, but just before the future mayor comes into shot, the design on the front changes completely. (00:38:15)

Back to the Future mistake picture

Continuity mistake: Beginning of film. When Marty arrives at Twin Pines as the Doc requested he cruises up alongside Einstein on his skateboard, saying "Where's the doc, boy?" There's a cut to the truck opening, then back to Marty, and for some strange reason the yellow wheels on his skateboard have turned pink, but the reflection on the wet car park is still yellow. It cuts back to the DeLorean coming out of the truck then back to Marty, and his wheels are yellow again. This doesn't happen in the VHS version. (00:17:40)

Revealing mistake: When the DeLorean is about to time travel for the first time, the fuel trails to achieve the following fire trails are already visible on the pavement. (00:22:00)

Sacha

Dr. Emmett Brown: Don't worry. As long as you hit that wire with the connecting hook at precisely 88mph the instant the lightning strikes the tower... Everything will be fine.

Trivia: In the battle of the bands scene, when Marty introduces The Pinheads, Huey Lewis, who provided "The Power of Love" for the film's soundtrack, plays the second judge from the left, and is the one who eventually says, "You're just too darn loud." (00:07:40)

More trivia for Back to the Future

Question: Right when Marty gets back to Doc before he goes back to 1985, he's praising his dad's actions of the night. One line that's bothered me ever since I can remember is "My dad laid out Biff. He's never stood up to Biff in his life." And then the Doc pauses for a second and gets a strange look on his face and says, "Never?" To that, Marty says, "No, why?" and the Doc shrugs it off saying, "Nevermind." What's Doc thinking? The best I can come up with is that he's wondering what effects it'll have on the future, but that's a rough guess. If anyone out there knows, I'd be happy to hear it.

DenizenZERO

Chosen answer: I think that is *exactly* what he is thinking. He realizes that by standing up to Biff, George may have irrevocably changed his personal future, and therefore affected Marty's future as well. This is exactly the sort of thing Doc was so eager to prevent by refusing to hear any information about the future.

Phil C.

Answer: It would have had to be something that would have happened anyway without the interference, otherwise Marty wouldn't have originally existed.

terry s

Answer: In the novel Marty adds that George is also thinking about college now. Doc says that this might delay Loraine and George having kids for awhile and adds that Marty might find himself like 10-14 years old when he gets back to 1985.
