Corrected entry: At the point where Marty shows the Doc the video camera from the future and hooks it up, the recording plays. Then Marty fast-forwards the video. While fast-forwarding, when the Doc lifts the camera up and turns it around to admire the technology, the blue wire falls off the video camera. When resuming play after a few seconds, the video turns out to be just fine, though without the cable, the image/sound or electricity should have been interrupted. (00:35:15)
Corrected entry: Whenever someone talks about the 1.21 gigawatt's needed to power the DeLorean, they say it as "jigawatt" instead of "gigawatt" (subtle difference). There is no such thing as a "jigawatt". A "gigawatt", however, is possible, however unlikely (ref. Doc says the only way to have 1.21 gigawatt's instantly is with a bolt of lightning).
Corrected entry: In order for the time machine to stay in the same place geographically, it would have to move with the Earth's revolutions over the years. Otherwise, even a small time jump could leave the person miles from where he started. So the Doc is wrong in saying that it can't move through space as well as time.
Corrected entry: To get Marty back to 1985, Doc has to time the Delorean's trip just right to have its hook hit the wire when the lightning strikes. Putting aside the wild notion of timing something to the exact millisecond, the alarm in the Delorean goes off while the car is stalled. Marty takes several seconds to get the car started again, which is going to throw off all of the calculations required to get the Delorean to the lightning strike and make Marty miss it.
Corrected entry: After the Delorean goes back to 1985, it crashes into the building in front of it (a newsagents, or some kind of store). If it was going at 88MPH, shouldn't it be totally wrecked? No wonder it doesn't start. (01:37:55)
Corrected entry: Near the beginning when Biff returns George's crashed car, after the discussion about who will pay for it etc., Biff goes to the fridge and gets a beer. He complains that George only has 'Lite' beer for him, but if you look on the fridge door it seems there are 3 cans of what appears to be 'regular' Budweiser. (00:13:05)hushkit
Corrected entry: When the DeLorean is struck by lightning, there is a second stunt person in the passenger seat of the DeLorean. Since they never re-shot this scene, you can see it in all three BTTF movies. (01:36:35)
Corrected entry: After the DeLorean arrives in 1955, the speedometer shows the car is decelerating. However, just before crashing into old man Peabody's barn, the speedo shows it go down to 49, then start going up again. (00:30:15)
