If Doc Brown took the DeLorean back to 1885, and the lightning strike blew out the time circuits...and Marty took the DeLorean back to 1885, and the gas tank got shot out by the Indians, but the time circuits still worked...why couldn't they use both DeLoreans (which would coexist in 1885) to make one fully functional DeLorean, instead of having to use the train? (I must have watched the whole trilogy about six times on Starz over the break...)

As soon as they took the delorean from where Doc Brown stashed it then it would no longer have been there for marty to use.

Whenever you notice something like that, a wizard did it. ;)

Okay, honestly maybe they screwed up. The BTTF trilogy has all sorts of mistakes so try not to look too hard for them. Check out this page for an interesting look at a bunch of time travel movies.

Actually I don't get that they screwed up. I mean if they took the original delorean then Marty would have never made it back to 1885. Also according to their physics, it wouldn't have created a paradox. It would have just made Marty fade away from Doc's 1885 timeline just like he almost did in the first one. ;)

It would have worked just fine, they'd have just had to add a new gas tank in 1955 before sending marty back to 1885.

The problem wasn't a lack of a gas tank, it was a lack of gasoline. They could have fixed the gas tank in the delorean marty brought back easily, the problem was filling it.

Couldn't they put basically anything in there? Like garbage, what was that Mr. Fusion thing in the back of the Delorean about...

Mr. Fusion only replaced the nuclear reactor which was only used to power the time circuits. The car itself still used the internal combustion engine.

Also...about the paradox thing. If you remember in the first one, when Marty went back to 1985, he was able to see himself going to 1955 after Doc got shot. My point is that he did coexist with himself and there was totally no fading going on there, even though he coexisted with himself for a matter of minutes. Because of this, I'm starting to wonder if that stuff ever really happened.

you're not getting the paradox... the paradox is that if marty and doc, in 1885, pull the delorean out of where doc had stashed it, then marty couldn't have recovered it and used it to get to 1885, and then he couldn't have helped doc pull it out of where it was stashed.

they didn't need to pull the delorean out. just get a quarter tank of gas from it.

I didn't originally see that bit of paradox, but you sum it up nicely...all they needed was a little bit of gas to get it up to 88mph. And I know that there are small inconsistencies in movies...however, when I thought about it, this seemed to be a major one, like if in the first one, Marty actually had taken back a second shot of plutonium for the DeLorean, but they totally glossed over it just to get to the lightning-strike plotline. And I know it's just a movie...I just thought this would make for some lively discussion when I thought of it...

If the Doc in 1955 sent Marty back to 1855 in BTTF could have just prevented it all by not building a time machine at all so nothing ever happens in 1985, would that totally screw up the universe?

It couldn't happen, because he did build the time machine, so he never went back in time and told him to not build it.
