Corrected entry: This would only be noticeable to the true movie geek, but when Doc and Marty are looking at the map to plan their trip back to 1985, Clara is standing in the background waiting for Doc to pick her up as he promised he would do. Since he doesn't show, she apparently rents a wagon herself and. . . well, the rest is history.Nicki
Corrected entry: When Marty leaves for the future at the beginning of Part II, Biff is in his red tracksuit about to wash their cars and Marty's black truck is in the garage. Then in Parts II and III, Marty and Doc make plenty of changes in the past and Doc staying in 1885 would greatly change things on Marty's return to 1985. But when Marty's returns to 1985 at the end of Part III, Biff is still in his red tracksuit about to wash the cars and the same black truck is still in the garage.Gavin Jackson
Corrected entry: If the 1955 Doc saw his tomb and sent Marty to 1885 he shouldn't be surprised to see him in 1885, since the Doc that's in 1885 is the same one who sent him there in 55, and hence has already seen his tomb. Some people argue it's not the same Doc, but time travelling doesn't magically create a new human being! The 1955 Doc sends Marty back to 1885, ages 30 years, invents a time machine, travels around, and ends up in 1885. 30 years may dull the memory a bit, but I think you'd remember sending someone into the past to rescue yourself...
Corrected entry: In the last scene in 1885 where Marty, Doc, and Clara are on the train racing toward the bridge, Marty keeps yelling at Doc on his walkie talkie to tell him the gauge readings. But after Doc sees Clara on the train, he tries to rescue her and Doc is no longer holding his walkie-talkie. Doc is holding on to the train with one hand while reaching for Clara with the other. Doc's walkie-talkie is no longer anywhere in sight. Marty sees all this but he nevertheless keeps yelling into his walkie-talkie right to the end as if that is how Doc could hear him. Marty does this even when he is facing forward all by himself in the DeLorean. Who is Marty talking to on the radio? It can't be Doc.
Corrected entry: Doc's tombstone was placed by his "beloved Clara". However, that was discovered (and carved) before Marty went back and changed the past by him and Doc rescuing Clara. So how did Doc meet Clara without Marty being there, given that the ravine was already called Clayton ravine, meaning that by definition she must have fallen in? Bit of a paradox, methinks. Even assuming he met her at the station, then after that her carriage fell into the ravine, the timings just don't work at all - she couldn't have fallen for him in minutes, and/or couldn't have had her name on the gravestone given that she fell in the ravine before Doc was shot.
Corrected entry: In the scene where Doc explains to Marty the idea of pushing the DeLorean across the bridge, Marty points out that the bridge is not completed yet (in 1885). Doc says that Marty is just not thinking 4th dimensionally, and once they return to 1985, the bridge is complete, safe and still in use. Unfortunately, the whole idea of returning to the exact same point in space, but a different time, is fundamentally flawed. If the DeLorean was to return to the same point in SPACE, only 100 years later, it would have to account not only for the completion of the bridge, but to all of the other changes to the physical environment. For example, in 100 years, the North American continent would have moved because of continental drift, the Earth would have rotated on its axis, so that point in space would no longer be Hill Vally, CA; the whole planet is revolving around the sun, therefore, the planet Earth wouldn't be in that exact point in SPACE, the sun is revolving around the galaxy, the galaxy moves through the universe, and on and on. Anyway, the DeLorean couldn't have shown up on the completed bridge 100 years later because Earth is moving through space in several different ways.
Corrected entry: When the 1955 Doc sends Marty back to 1885 he points to a cave where to hide the DeLorian left of the track that Marty takes (directly towards that cinema screen). In 1885 then, Marty takes a U-Turn to flee from the Native Americans. Assuming a 180 degree turn, the cave to hide the car must be on the right hand side. However, the cave appears directly in front of him.
Corrected entry: When the DeLorean suddenly appeared in 1885, the Indians have absolutely no reaction at all. There is no possible way that they wouldn't have been the least bit spooked or confused, and we should have seen some semblance of this in their actions, but they just keep charging on like nothing happened. It'd be like a an alien spaceship appearing out of nowhere in Times Square and people not even batting an eyelash.Knever
Corrected entry: Doc Brown can build a time machine but is unable to figure out how to build a still to extract pure ethanol from Whisky in order to use as fuel for the DeLorean. He stated to Clara that he is a "student of all science" so this should include chemistry. Chemists know how to build a still. Doc, however, tried to fuel the car with strong Whisky without distilling it.Acteon
Corrected entry: Freeze frame is recommended when trying to catch this one. When Clara rides out of the stable her hat falls off, however in the next shot of her turning the corner you can see the silhouette of the brim, indicating that it has returned to her head.
Corrected entry: Right toward the end of the movie, a split second before the Train crashes into the Delorean, underneath the Car you can see that a fireball bursts, causing the effect.
Corrected entry: When the DeLorean is destroyed by the train at the end, why does the train smash through it, instead of just pushing it back down the tracks? Even if Marty had put on a parking brake (which we don't see him doing) it doesn't seem like it would be strong enough to withstand the force of the train. Even cars that are sitting perpendicularly on railroad tracks get pushed along by fast-moving trains, so why not a car that's specially designed to move on the tracks?Krista
Corrected entry: After the DeLorean is destroyed by the train, Marty goes to get his truck, picks up Jennifer, almost races with Needles, and then finally returns to the scene of the accident. Isn't it odd that a car was hit by a train, yet there are no emergency vehicles anywhere around, or that the train didn't stop afterward?BGraz
Corrected entry: When the locomotive crashes from the bridge, there is a huge explosion (may have been added digitally in a later version). However, there are no explosives in a steam-engine, only water and wood.
Corrected entry: The main plot device is the lack of petrol. The Doc has an ice generating machine and lamp oil. The ice-generating machine is steam driven and works at ambient temperature. Therefore it is fair to assume that it uses pressure transformation to achieve freezing. It should be fairly simple to rebuild the compression equipment from the icebox into a small scale cracking unit. The required technology is similar. Cracking is the process of breaking down heavy oils like lamp to light ones like petrol. At this point in the film they have several days which should be plenty of time to do this. This would be a much safer course of action.
