Back to the Future Part III

Corrected entry: At the onset of the film, Doc and Marty discover Doc's grave from 1885 with the dedication by Clara Clayton on it. Now remember, this was before Marty had gone back to 1885 to meet Doc and further influence the happenings in that year, which included their chance meeting with Clara when she almost died. Even without Marty's influence in 1885, history of the film series up to that point said Clara went over the cliff and died. So therefore, it is inconceiveable that Clara could have lived to even meet Doc to put the dedication on his grave, as he died a few days after she would have.

Correction: You're forgetting that the mayor reminds Doc that he had volunteered at the town hall (before Marty's arrival) to meet the new schoolteacher at the station. So without Marty's intervention, Doc would have met her there and she wouldn't have died in the ravine. But since he *didn't* meet her at the station because of what Marty told him, history played out as originally fated and she lost control of the spooked horses.

Corrected entry: The gravestone as seen by Marty and Doc in 1955 is in the same mint condition as when we later see it being made in 1885. Given that it has remained outside for 80 years, shouldn't it be more weather beaten or damaged?

Correction: Not really; I've visited dozens of graveyards and seen thousands of tombstones. Solid granite tombstones hold up very well in dry areas, like the setting of the graveyard in the movie. Tombstones in climates that have a regular change of seasons have more weathering damage.

Corrected entry: When Marty suggests taking Clara back to 1985 with them, Doc refuses, saying that it would disrupt the spacetime continuum. Since she was supposed to die in 1885, she's not even supposed to be there. Taking her back to the future would fix the problem, not make it worse.

Correction: She was supposed to die, period. Taking her to the "present" would disrupt the space time contimuum for the "future". She'd affect the world of 1985 in ways it wasn't meant to be affected thereby altering the timeline. Since she didn't die, the most logical "place" for her is her own time.

Corrected entry: Throughout the films, the time jump occurs at the end of the flaming skid marks. But, when Marty crosses the bridge near the end, the flames go right across the incomplete section even though the DeLorian has already gone at the start of them.

Correction: This is just wrong. For a start, the very first time jump we see in the first film ends up with Marty and the Doc slap bang in the middle of them. If the car disappeared at the very end of them, they'd have been run over. See:

Gary O'Reilly

Corrected entry: In the scene when Doc enters the saloon after having his heart broken by Clara, he is approached by a barbed-wire salesman. It appears that the salesman is wearing hearing aids. Obviously impossible for that time period.

Correction: There is nothing like a hearing aid visible in his ear.

Corrected entry: When Marty is sent to 1885, he arrives at September 2nd, 1885. Then, Doc has to meet Clara at the station the next day, September 3rd. But when Doc and Marty are figuring out a way to reach 88 miles an hour with the DeLorean, the calendar shows "September 4th" and they still haven't met Clara.

Correction: Marty arrived on September 2nd, but he didn't meet Doc until the 3rd (he spent the night at the Mcflys' house). That means the mayor came by to see Doc on the 3rd about meeting Clara on the 4th, which is the day Doc saves/meets Clara.

Corrected entry: Back in 1985, Marty dives out of the DeLorean seconds before a train hits it. He lands on his front, then turns over to see the smash. In the next shot he is crawling on his front.

Correction: Marty sits up to see the crash. So then he would be able to lean forward from a sitting position and put his legs behind him to crawl on his front.

Corrected entry: When Clara and Doc are hanging off the train barely, Marty lets the hoverboard go so Doc can save himself and Clara, which he does. When he pulls away from the train, the camera is shooting from Marty's P.O.V. and it shows Doc pulling ahead of the train and past the Delorean. He would slow down if anything, not speed up, especially holding Clara.

Correction: There is no way to know how a hoverboard from the future is supposed to perform when accelerated to 80+ mph from a moving object, as its limitations and/or functions are never revealed to the viewer.


Corrected entry: When the car and train go past the windmill, Marty yells to Doc they are going over 60 and he'll never make it back in time. But about a minute later Marty looks at the speedometer and it just then passed 60.

Correction: Once the train reached its top speed, it was up to the "logs" to make it go faster. This was not done by a steady acceleration, but rather a burst that increased the DeLorean and the train's speed, which remained at that speed until the next log. If you will notice, after the log blows that accelerates them to just over 60 mph, the car remains at that speed until the last log blows, so the speedometer in the shot you referenced should still be reading just over 60 mph even a minute after Marty tells Doc they just passed 60 mph. Not a mistake.


Corrected entry: When Doc and Marty are in the old mine looking for the Time Machine they bust open the sealed entry and find it. The entry is too small to get the Time Machine out. Even if we assume that they made the entry larger, how did the 1885 version of Doc get the Time Machine into the room through the smaller entry back in 1885?

Robert Sullinger

Correction: In Doc's letter to Marty he said he had been living happily there for several months, which is plenty of time for a man of the Doc's abilities to strip the car down and rebuild it in the mine shaft.

Mad Ade

Corrected entry: Doc wrote the letter (which was read by himself at the start of the movie) and it mentioned the name Clara. Marty went back to 2nd Sept 1885, and met Clara by the cliffs later on. But that letter was written 1st September 1885, before Marty arrived. How is this possible?

Correction: The letter never mentioned Clara. They didn't find out about her until they saw the gravestone.


Corrected entry: How come the Native Americans aren't surprised at all when a racing Delorian appears from thin air in front of them, in dazzling futuristic lights?

Correction: Who's to say they weren't? Anyway, these appear to be warriors, who would likely consider it dishonerable to show fear of the unknown.

Correction: There isn't a truck in the background. Upon closer examination, it appears that it is merely the visible tip of a nearby mountaintop.


Corrected entry: At the beginning of the movie in 1955, Marty has Einstein with him and left him with Doc of 1955. At the end of the movie Doc from 1885 went back to 1985 to see Marty and said he had to come back for Einstein, but wasn't Einstein with the Doc of 1955. So how did Doc get him back, is there some kind of explanation?

Correction: Marty never has Einstein with him. The dog in 1955 was named Copernicus. Einstein had first been in 1985 (first movie), then travelled into the future with Doc, where he was cryogenically frozen in a kennel while Doc and Marty tried to straighten things out (second movie). Doc was then sent to 1885, made a new steam-powered time machine and went to the 21st century to "come back for Einstein", before dropping in on Marty in 1985 and say goodbye.


Corrected entry: As the train approaches the DeLorean there is no wooden scaffold to hold the rubber tyres acting as a buffer, yet in the next shot a few seconds later, there is a wooden scaffold on the cow catcher.

Correction: The next shot is after a cut, in which time Doc could have mounted the (obviously home-made) scaffold on the cow catcher.


Corrected entry: The arrow stuck in the side of the DeLorean is perpendicular to the car, but that side wasn't facing the Indians during the chase so they couldn't have hit it.

Correction: There are several times during the chase where you see the Indians ride up on both sides of the DeLorean, including the driver's side. The mistakes, as noted elsewhere, is that the car after all these shots jumps to a point in front of the Indians, and that the arrow appears out of nowhere, but yes, there are occasionally Indians who pass the car on the driver's side.


Corrected entry: When Doc is telling Clara he is leaving and will not see her again, and he tells her he is leaving in a time machine. Clara tells Doc that she also read the Time Machine and is a fan of Jules Verne, but the Time Machine was written by H. G. Wells.

Correction: Clara says: "I understand that because you know I'm partial to the writings of Jules Verne you concocted those mendacities in order to take advantage of me." At no point did Clara actually SAY that Jules Verne wrote The Time Machine. She does not mention The Time Machine at all, nor would she, as it was not first published until 1895, 10 years after the events of BTTF III.

K.C. Sierra

Corrected entry: Given that Doc is so concerned about influencing future events, why does he set up shop right in the middle of town (creating a lot of loud and noisy inventions) and attend town meetings, and volunteer to pick Clara up at the train station? He should be a hermit, living as far away from people and civilization as possible.


Correction: It seems like Doc doesn't really care about time travel anymore, and that in the old west he decided to start a new life. It goes along with Doc saying "Well, I figured 'what the hell'" in the first movie in response to Marty asking him about not influencing future events. To him at this point, it doesn't really matter to him.


Corrected entry: When the 1955 Doc Brown and Marty went to retrieve the DeLorean from the cave, the passage between the room containing the car and the rest of the mine was rather narrow, and to remove the support beam on either side of the opening to widen the opening is to risk a cave in. How did the car get in there or out? Piece by piece?

Correction: We saw them dig out a hole into the room with the DeLorean and stopped when they could get a good look. It is entirely possible that they made a bigger hole off camera when it was not necessary to show it and brought the car out then.

Corrected entry: When the DeLorean travels forward through time at the beginning of the first movie, the car gets covered in ice. During all other subsequent time travel, this does not happen.

Correction: Actually, it does. It looks like steam coming off the car.

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.

Jennifer: Excuse me, Doc Brown. I brought this message back from the future and, well, now it's erased.
Doc: Of course it's erased.
Jennifer: But what does that mean?
Doc: It means your futures haven't been written yet. No one's has. Your future is what ever you make. So make it a good one, the both of you.

Trivia: The band playing at the Hill Valley festival is rock band ZZ Top (two guys with long white beards playing guitar, and a drummer), who wrote songs for the film.

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?


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.


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.
