Continuity mistake: When Marty is being chased on the scooter turned skateboard, he is hanging onto the corner of a blue truck. Biff tries to smash him between the two, and the camera shows him pulling himself along the side of the blue truck, then hanging off the back corner again. (01:04:10)

Continuity mistake: When Biff is grousing to George about who will pay his cleaning bill (for spilling beer on his jacket when he wrecked George's car), there is a picture frame on a stand in the background. It's initially facing fairly rightwards, but in the next shot of the argument, it's facing more towards the camera. (00:11:55)

Continuity mistake: In the escape from Biff on the skateboard, Marty collides with a couple near some steps. His skateboard is left at their feet, but after a cut his skateboard's now behind the woman's head in an ideal place for Marty to grab it. The papers thrown in the air suddenly multiply and appear on the ground (under the people, which means they must have dropped the papers first before falling over!). (01:04:15)

Continuity mistake: When Marty and George are in the cafe talking about Goldie Wilson being mayor, George's head is turned facing Marty, but the next second his head is turned the other way. (00:40:35)

Continuity mistake: Towards the very end of the film when George and Lorraine are unpacking George's new book, you will notice in the close-up of Lorraine's hands that they are actually someone else's for that shot. They are very aged and much larger than her real hands, which you can compare right away when the camera goes back to full view. (01:49:25)

Tiffany Fife

Continuity mistake: When Michael J Fox's parent kiss and the family picture (with everyone standing on the grass) gets fixed, Michael places the photo on the guitar, gets very happy and starts playing the guitar enthusiastically.

Continuity mistake: Near the beginning, right after Einstein time travels, Doc walks up to the time machine and says it's cold. He then opens the door and greets Einstein. In this split second you can see Einstein's stopwatch has a non-illuminated LED display, but in the next shot the face has changed to the bright red numbering. (00:23:10)

Continuity mistake: When Marty arrives at the Twin Pines Mall at the beginning of the film, he drops his skateboard behind the DeLorean. When Doc starts the car with Einstein in it, the skateboard disappears. (00:19:05)

Continuity mistake: When Marty leaves the Peabody farm and turns onto the paved road, it has solid white lines marking the sides of the road. A few seconds later, Marty is shown driving down a road without white lines on the sides, even though he's apparently only driven a short distance down the road. (00:33:30)

Continuity mistake: During dinner, when old-Lorraine says "We all make mistakes in life, children", she swaps from having one hand on the glass to both hands, between one frame and the other.

Continuity mistake: When Marty rides to the mall he is riding his skateboard, but after Doc comes out in the car, it's gone, then at the end of the film when Doc drops off Marty he has it again. (00:18:40)

Continuity mistake: When the DeLorean sets off for the lightning strike, you can see it leaving tracks and spray on a wet road, later there is a close up of one of the wheels, which shows the road to be dry. Throughout this scene the road appears to alternate between wet and dry, during what is supposed to be a storm. (01:39:00)

Continuity mistake: Lorraine Baines' hands are on her hips, a brief cut to Marty and back and she now holding a cup and saucer at chest height. You could argue she had enough time to pick it back up, but this would seem odd as she's only just put it on the table. (01:43:55)

Paul Andrews

Continuity mistake: At the beginning, when Michael J Fox is cranking up the amplifier, the dial marked "Primary power" initially rises from 100 - 120, then when he turns the "overdrive" knob, it's back at 110 and goes to max. (00:03:15)

Continuity mistake: When Biff and his goon friends are in Biff's car, as they chase Marty on his borrowed 'skateboard', the car's rearview mirror repeatedly disappears and reappears, and the side mirror changes from round to square repeatedly. (01:06:50)

Trivia: Eric Stoltz was originally cast as Marty. After filming quite a few scenes they realised his acting style was too dramatic for the humor desired, so they cast Michael J Fox (who they couldn't originally get because he was busy with the TV show Family Ties). Filming was on weekends and nights around his TV schedule and using his double at other times.

Question: What does the saying "Why don't you make like a tree, and get out of here", mean?

Answer: It's a way of saying "scram" or "get lost." But Biff is so dim, he doesn't realize he's saying it wrong; the expression is "make like a tree and leaf", with the joke being that "leaf" is meant to sound like "leave."
