Back to the Future Part III

Corrected entry: What are Great Plains Indians doing in California?


Correction: The cavalry are chasing them so they may be on the run. The US Army pursued some Native groups deep into Mexico, so it's hardly unlikely for them to have fled this far.


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.

Correction: Freeze frame isn't recommended - it is required. This posting is invalid, per the rules of this site.

Corrected entry: When Doc and Marty locate the time machine in the mine/cave in 1955, the door/entrance to the mine cave is too small to have been used in 1885 to get the time machine into the mine cave. Others have said that Doc had the intelligence and time to disassemble the car/time machine, carry the parts in and re-assemble it inside the mine/cave. The problem with this is that while many parts (engine, doors etc.) could be disassembled, the body and frame can only be disassembled so much, they would still be too large to get through the door. Doc would have had to cut them up, carry them in, and then weld them back together. There were no signs of a welding process (weld bead) on the roof, which is part of the one-piece body. Since the body is stainless steel, the welds could not be sanded down and painted over, and there is no paint.

Correction: We only see ONE entrance to the mine. There could have been several more that were big enough to fit the DeLorean. Also, there most certainly would have been many large entrances back in 1885, when the mine would have actually been in use.


Corrected entry: In the letter the Doc sends to Marty in 1955 telling him where to find the time machine and telling him not to come back to 1885 to rescue him, he says he has met a wonderful woman and is thinking of settling down with her. When Marty goes back to 1885 the day after the letter was sent, the Doc has not met Clara yet and does not appear to have any other female attachments.

Correction: Doc does talk about settling down in the era, but makes no mention of meeting a woman in his letter.

JC Fernandez

Corrected entry: Doc is always banging on about making as little impact as possible in his new life as an inhabitant of 1885, yet the method of exit he chooses will change hundreds of lives and cause huge disruptions to all sorts of timelines. The train they destroy would not have been easy to replace, and would have been used by hundreds, maybe thousands of travelers to get to places they are now not going to get to, to meet people they are now not going to meet, to start family lines that now don't exist, and so on on so on. Now that Buford is no longer a threat, a far better alternative would be for Marty and Doc to leave town and live quiet, anonymous lives somewhere isolated - something Doc has already thought of and a far better idea than their returning to the future in such a damaging manner.

Correction: This is the final step in Doc's character development throughout the series. Initially, he is very concerned about the effects of altering the past, but he begins to ease up on these beliefs as the series progresses [hence his speech to Jennifer about her future not being written yet]. He has come to understand that the future will write itself and that any minor meddling by himself and Marty will not have the disastrous results he initially believed. This is why he wasn't concerned about building ANOTHER time machine in the 1800s.

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.

JC Fernandez

Corrected entry: At the beginning, after Doc sent Marty back to the future, you can see Marty hiding behind the cars before he runs out.

Correction: Of course he was hiding behind the cars. He had to prevent his past self from seeing him. He then comes out when he's sure that the past self has gone.

Corrected entry: In the opening scene when Doc wakes up he turns on the TV to hear "Hey kids, what time is it? It's Howdy Dowdy time." Doc, on the phone, says the time is 7 o'clock AM. Any smart baby boomer knows that Howdy Dowdy aired at 5:30 PM EST. (00:05:17)

Correction: Look at the mass of electronics on top of the television. It's likely that Doc has constructed a recording device and is using a recording of Howdy Dowdy as an alarm clock (remember his facination with the modern video camera in Part 1). We also know from the beginning of Part 1 that Doc has an obsession with setting alarm clocks.

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: When Marty and Doc first discover the gravestone in 1955, watch closely as Marty puts his hand on it. It wobbles slightly, revealing that it's a prop made of lighter material as opposed to actual stone.

Correction: Old gravestones may wobble.

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: Once Bueford went to jail, there was no hurry to get back to the future; as they did not have to leave before one of them got shot. Bearing that in mind, why did they chase after the 8 o'clock train? They didn't have much time to do that, which made it extremely difficult. They could've easily just used a train on a later date, one with plenty of time to plan out the experiment.

Correction: Just because the known danger has passed certainly does not mean that all danger has. That uncertainty would be more frightening to me than knowing the exact moment of my death. They only knew that Doc wasn't going to die until such and such date. Now that they've changed that, who knows what could happen. Rattlesnake, stray bullet, etc. It's best to get back as quickly as possible.

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: 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.

Correction: This is already listed as a mistake.

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.

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)

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.

More quotes from Back to the Future Part III

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.
