Question: The ending of Back to the Future, Marty says he's not going to the lake as the car is 'wrecked'. All the family react as if he's talking about the BMW. They rush out and see it is fine. But they know Marty has the Toyota truck - why would they not think he meant his car is wrecked'? I know he says car not "truck" but he's talking about going up to the lake - he wouldn't be going in his Dad's BMW. So is this a mistake or bad script writing? (01:49:00 - 01:51:00)
Answer: It would've simply been down to the pure shock of what Marty was saying. The second he said "The car's wrecked", they dropped what they were doing and went to check. They didn't even care about the first part of Marty's sentence at this point, as all that was going through their heads would've been "Has something happened to the car?"
Question: Given that the entire McFly family's circumstances have changed at the end of the movie due to Marty altering the past, shouldn't Marty's whole life have gone down a completely different path from childhood on? What are the odds that he even still knows Doc and Jennifer in the revised 1985 (let alone has the exact same date planned with Jennifer for the very same evening), given that everything else has changed?
Answer: The suggestion is given that he was the only "normal" person in the family and when he changed the past his parents and siblings became more "normal" people as well whilst he stayed as he was, despitegrowingup with different parents and siblings, since he was "normal" anyway. This totally ignores the linear timeline idea given during the entire movie, but it's obvious that was the idea.
You're absolutely right about Marty being the only "normal" one in the family, but that doesn't ignore the linear timeline idea. There are two different Marty McFly's by the end of this movie. There's the one we follow, who grew up with unhappy parents, and then there's the other Marty McFly who grew up with cool parents. We see the 2nd Marty go back to 1955 when Marty gets back to the Twin Pines mall. The idea isn't to ignore the linear timeline idea, but rather to imply that unhappy parents or not Marty will still always be Marty.
Except for the fact Marty kept being in danger of disappearing if his parents wouldn't get together. If his old self would disappear from his parents not getting together then so he should if his entire life is different and he would be a different Marty just like his siblings. Even if it's only memories rather than an entire personality.
Answer: It's definitely a paradox. Marty actually goes back to the life of 2nd Marty, but if that's the case then original Marty should have still faded away since he created a new timeline when he gave George confidence. Original Marty shouldn't exist anymore at all, he should have faded completely away on the stage. I've said it before and I'll say it again: time travel movies are a mess.
The new Marty isn't a different person entirely; he's just the same guy who was raised in a slightly different environment to the original timeline. Marty's actions in 1955 have ensured that his parents will have three children, and he will be one of them. His existence is completely secured in the timeline.
Corrected entry: Do you honestly think that Marty's parents wouldn't think it was the slightest bit odd that their son happens to look and talk and dress EXACTLY like the boy that hooked them up in high school?
Correction: Ever realized all of a sudden that someone you know bears a resemblance to someone you knew a long time ago? Sure - it happens... (either Marty's parents haven't reached that point yet, or they simply never noticed - it's been 18 years, remember...)
It's been 30 years and Marty was only around for a few days. Can you remember everyone you only saw for a few days 30 years ago? I've got a great memory and I have a hard time remembering someone I met even a few years ago.
True, I went to school for 7 years with one guy who was in all my classes but didn't recognise him when my mother pointed him out 5 years after we went to different secondary schools.
Question: Near the end of the movie, George and Lorraine say that if it hadn't been for Biff, they never would have fallen in love. Shouldn't they really be thanking "Calvin 'Marty' Kline" for getting them together?
Answer: I agree with you, but the idea is that, if George hadn't rescued Lorraine from Biff in the parking lot, they wouldn't have fallen in love. It's dark as hell to wax nostalgic about an attempted r*pe, but there you go.
Totally agree with your answer. Would add that Lorraine already knew who George was but was unimpressed and had mostly written him off as a goofy nerd. It was George saving her from Biff that totally changed Lorraine's perception. Otherwise, Marty's attempt to push them together probably would have failed.
Answer: Why wouldn't he go in the BMW? Going to the lake doesn't mean off-road driving, it might be a nice paved road all the way to a touristy spot. I don't think it's a mistake or bad writing.
Actually, Biff comes up to him with the keys to his truck, saying it is ready for his trip. So he was going with his truck.
