Back to the Future Part III

Continuity mistake: When Doc and Marty are chasing the train on horseback, Doc gets on the train first and his horse pulls forward. Then when the camera shows Marty on his horse, another horse can be seen in front of him. When Marty jumps on the train, his horse falls back. But in the next shot you can still see the horse as it moves off camera. (01:30:55)

Factual error: Sierra #3, the locomotive used in BTTF 3, is a 1891 Rogers, despite this movie being set in 1885. (00:40:45)

Factual error: In the scene where Doc and Clara are playing with a telescope at night, the moon is seen twice. The phase of the moon appears to be a waning gibbous. Though the phase of the moon on the night of September 5th, 1885 at pacific time was waning, it was actually a waning crescent, a much different looking phase of the moon. I looked this up on the United States Naval Observatory website.

Factual error: The steam locomotive in the film is of a 4-6-0 wheel arrangement and is lettered as Central Pacific no. 131. The Central Pacific did have 4-6-0 engines in 1885, but according to the company's locomotive roster, the number 131 belonged to an engine of a 4-4-0 wheel arrangement. Also when the locomotive is uncoupled it shows a Janney (fist style coupler) - that style wasn't invented until 1890. The locomotive would have used a pin and link style connection.

Continuity mistake: When Marty is about to go to 1885, before Doc shoots his gun, you can see the coils on the face of the DeLorean is brown, later when he is driving toward the screen, the coils are clear silver again.

Continuity mistake: When Doc and Marty get on the train at the end, Marty has some trouble getting on, and note that his hat falls off in the sequence, but in the next shot when Doc and Marty fall the hat is back on. (01:31:15)

Brooks Jr.

Continuity mistake: When the Doc enters the destination time into the time circuits when he is sending Marty to 1885 from 1955, the time/date etc. Go in as he's typing it. However, in the previous films and later in the 3rd film when traveling back to 1985, the enter button must be pressed before anything appears for the destination time.

Other mistake: When Clara is waiting for the train to stop at the train station and the train has steam coming from in front of the wheels, as it passes by the camera it jolts the camera. (01:20:20)

Continuity mistake: At the end of the movie, when Doc and his family leave in their newly built train, the neon lights that flash over the front of the train go from left to right. In the next shot, where the train actually rises from the ground, they go in the opposite direction. (01:51:05)

Continuity mistake: When Marty is at the shooting gallery at the party and has his go, he points the gun in the wrong direction but still the targets go down. (00:54:18)

Deliberate mistake: During the train sequence at the end of the film in 1885, it is blatantly obvious that the train is not going the speed that the DeLorean's speedometer is showing. In some shots, the train looks as though it is going little more than 20mph. (01:38:55)

Continuity mistake: When Doc and Marty are chasing the train, first their shadow is on the left of them, then in the next shot it's on the right. (01:30:40)

Continuity mistake: In 1885 Hill Valley, the hills are shown to be almost directly behind the courthouse, however in the previous films there was some distance between the two. This was likely due to the different shooting locations. (00:26:40)

Audio problem: When Mad-dog Tannen is standing over Marty, who is playing possum, you see Tannen cock his gun twice between two shots, although there is no sound effect for the first time. (01:27:50)

Continuity mistake: In the saloon, Mad Dog shoots at Marty, forcing him to dance. Marty goes into his moon walk dance, and just before he launches the spit jug at Mad Dog, he does a jump. Watch as he lands - the jug is suddenly 4 to 6 feet to the right of him.

Plot hole: Although Marty rips the fuel line, not all the fuel would have drained out of the tank. Only the fuel that was already in the fuel line would have leaked out, meaning it could simply be patched, bled and the engine would run without a problem.

Factual error: In shots of the town outside of the saloon in 1885 a modern day California flag can be seen. This flag was not used until 1911.

Continuity mistake: In the scene where Marty is driving the black Toyota pickup at the end of the movie, the truck's registration plate is missing - it can be seen when the truck is in the garage at the start of the film. Also the driver's door quarter light (vent window) is open. When we see the inside of the door it is closed. (01:41:45)

Continuity mistake: Just after Doc saves Clara from the ravine, the carriage flips on its side and rolls. In the next shot, it's stopped rolling and is falling neatly straight down. (00:41:30)

Plot hole: Doc could not have the copy of the pic of him and Marty at the clock of the tower, because Marty has it in the DeLorean when he comes back to 1985.

Suggested correction: The technology existed in 1885 to produce duplicate copies of the same photograph. The photographer who took it would certainly be able to do so there and then. Even if that wasn't the case it's not a stretch that someone of Doc's abilities could manage it so that he and Marty could each have their own copy.

Suggested correction: There are several instances of duplicate (doppelganger) items and characters in the same timeline throughout the BTTF trilogy. For example, the DeLorean itself exists two and even three times within the same timeline. Doc and Marty and Jennifer and Biff all exist as doppelgangers within the same timeline. So, a duplicate photograph should be no problem in a storyline riddled with such inconsistencies.

Charles Austin Miller

This is incorrect... there is only 1 Marty, 1 Biff, 1 Doc, 1 Jennifer and 1 DeLorean. Yes, multiple versions may exist at the same time but in no instance is there a copy of the original person or car. For example, in BTTF II in 1955 there are 2 Marty's at the dance at the same time but the 2nd newer Marty is the same Marty from BTTF I. There should only be 1 copy of the picture, on the other hand, because it has not (to the best of our knowledge) been time traveling. The only explanations (for it to not be a mistake and these are still guesses) could be that they had a second picture taken even though it might be an expensive and time consuming process or Doc Brown could have gone into the future and taken it from Marty and, therefore, the picture could exist twice in 1 time period.

The photo time-travels at least twice in BTTF3: Once with Marty in the DeLorean on the explosive return trip, and again a few moments later when Doc arrives in the steam-powered locomotive time machine. We can reasonably assume that there was another, time-erased meeting between Marty and Doc (possibly in the future) wherein Marty explained how the photo was destroyed, prompting Doc to go back to the Old West and procure the photo again. Same exact photo X2, same scene, just as there were multiple characters and vehicles in the same timelines.

Charles Austin Miller

Suggested correction: It's certainly possible that they got more than one photograph taken.

Greg Dwyer

Doc: Clara was one in a million. One in a billion. One in a googolplex!

Trivia: When filming the scene where Marty is being hanged from the clock tower, Michael J Fox agreed to really hang from the rope. Whilst filming, Fox held the rope away from his throat with his hand. At one time he wasn't holding the rope and was really being strangled. The film crew didn't realise, they just thought it was really good acting, until he passed out.
