Back to the Future Part III

Factual error: Though extremely modest on today's standards, the dress worn by Clara to the hoedown shows far too much cleavage for the time. No schoolteacher would ever wear a dress like that in the 1880s.

Continuity mistake: When Marty returns to 1985, he goes to his house and gets in his Toyota pick-up. Look closely behind his head when he first gets in the truck, there is no driver-side head rest. But when he picks up Jennifer, when they pull up to the stop sign the head rest is there. (01:45:00)

Continuity mistake: Watch the scene with the Indians (just as Marty sticks the DeLorean into reverse) and see the differences of how close and far the Indians are from the DeLorean. (00:18:59)

Continuity mistake: When Marty goes back from 1955 to 1885 and meets the Indians, note that none of the Indians shoots any arrows nor do any arrow hit the car. You can see that when he drives the car back into the cave. But when he gets back to the cave after the Cavalry ride, a long arrow sticks out on the side of the car. (00:18:10 - 00:20:00)

Factual error: When Marty goes to meet Mad Dog Tannen for the duel, in the background on the right side is the current flag of California. But that flag did not become the state flag of California until 1911, so would not have been around in 1885.

Revealing mistake: At the end, when the train destroys the time machine, right at the moment when it hits you can see a small explosion, which was used to trigger the destruction of the time machine. (01:43:03)

Factual error: In 1885 when Maggie McFly asks Seamus for a word, they walk into the other room and behind them are a few garments hung on pegs on wire hangers. The wire hanger was invented by Albert J. Parkhouse in 1903, eighteen years later. (00:25:50)

Continuity mistake: When Doc drinks the 'wake up juice', he runs out and puts his head in the horse trough full of water. However, after a shot to Mad Dog Tannen, his shirt is mysteriously dry again. (01:20:05)

Continuity mistake: When the train is coming and is about to run over the DeLorean, the shadow of the train on the wall shows that it is only the locomotive. When the camera changes view, it is a train with freight carriages. (01:43:00)

Continuity mistake: When Marty is being chased by the Indians, a wide shot with the DeLorean at the bottom of the screen coming towards us and the Indians following reveals the entire background for a mile or two. However, there are no cavalry visible anywhere despite the fact that they pass over the cave in the following shot only five seconds after the last Indian does. (00:19:15 - 00:20:20)

Revealing mistake: When Marty and Shamus are sharing a meal at the dinner table, Shamus passes Marty the plate of rabbit. As Shamus hand moves away to let go of the plate, to the bottom right hand corner of the plate, a purple patch appears briefly where the two M. J. Fox actors interact, an error with the Vistaglide camera tech used back then. Easier to spot on Blu Ray Version, better than DVD. (00:24:10)

Factual error: At the end of the train scene just before Marty travels to 1985, the train busts through a road block warning that there's only 1/4 mile of track left before the ravine. Keep in mind that the train is travelling at approximately 70-80 mph by this time. At 70 mph (and not even accelerating) it would only take the train 13 seconds to reach the ravine. The actual time in the movie is at least a minute. (01:40:31)

Continuity mistake: When Marty is shot by Buford, he is thrown off his feet and lands on his back. As he does, his poncho flips up, showing his shirt all the up to the middle of his chest. The stove door he is supposedly using as a bulletproof chestplate is conspicuously missing. (01:27:20)

Other mistake: When Marty returns to 1985 from 1885 the time machine is destroyed by a train. What is strange is that not only does the train not stop (which is mandatory in the event of an accident) but there is also no reaction from people nearby, such as those in the vehicles waiting to cross the track at the level crossing. Later, when Marty returns to the site with Jennifer, there is still no sign of police officers or other officials.

Continuity mistake: When Marty is about to go back to 1885, he starts driving and you see him pass the building: then when it shows the car's tires, you can see he passes by the same building again.

Continuity mistake: When Clara first sees the train and starts after it on horseback, it is on her right side. She is at the top of a hill and starts down after the train. In the next shot shown from the front of the train you see the horse appear so the train is on Clara's left. (01:34:09)

Continuity mistake: In the last fifteen minutes of the film Marty wears his Wild West clothes, including his brown woolen poncho. The front of the poncho is unmarked, completely intact. Shouldn't it have a bullet hole in it? (01:43:50)

Continuity mistake: When the DeLorean is being pulled by horses, the clouds in the sky change in the next shot. (00:38:50)

Continuity mistake: When Doc's about to send Marty back to 1885 from 1955, and Marty's dressed up...when Doc's walking back and forth loading up the car - look at the shadow from the building. You see it changes by several feet in a few seconds as the scene was obviously shot throughout the day. (00:16:35)

Factual error: In 1885, Hill Valley and its surrounding areas are shown as having a desert climate, when in both 1955 and 1985, the climate is grassland. In reality, Nevada County, California (where Hill Valley is supposed to be located) is and always has been grassland and forests, not arid desert.

Doc: Marty, the idea that I could fall in love at first sight! It's romantic nonsense. There's no scientific rationale for it.
Marty: Come on, Doc. It's not science. You meet the right girl it just hits you. It's like lightning.
Doc: Marty, please don't say that.

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.

More trivia for Back to the Future Part III

Question: When the 1985 Doc is suddenly transported back to 1885 at the end of BTTF 2 and Marty discovers that he has been murdered, because there is a Doc in 1955 that has already been born after the 1985 Doc has died in the West, why did he go to the trouble of going all the way back to 1885 when Doc was still alive? Is there any actual legitimate time travel reason for this, or did he just do it out of instinct to help his close friend?

chunkz87

Chosen answer: According to the letter, Doc plans to live out his life in 1885. But as it turns out, Doc gets murdered a week after sending the letter. Knowing that Doc's plan to live out his life don't come to fruition, and because he's a good friend, Marty travels to 1885 to save him.

JC Fernandez

Answer: Technically when Doc got transported to 1885, he should not have existed in 1955 because he died. This is the problem I'm having with part 3. The movie should not have happened this way. It should have been where doc did not exist nor the time machine. Part 3 should've never happened.

That's not how most time travel (if any) stories work. Just because someone dies in the past doesn't prevent them from being born since they were already born and alive before going to the past. Think of it this way, if instead of 1885 he travelled to 2085 and died, would that prevent him from being born? The only reason Marty was in danger of disappearing and not existing (i.e. being born) was because his parents were in danger of never getting together.

Bishop73

It was the 1985 Doc that went back to 1885 so he would still be alive in 1955.

The Doc that got sent to 1885 was the Doc from 1985 so therefore it wouldn't have affected 1955 Doc at all.

The one in 1955 hasn't done anything 1985 Doc did.
