The Time Travel Paradoxes of Back To the Future
brumgrunt sent in a fun little piece to get your brain going on a cloudy monday morning. Despite countless viewings of BTTF I still never thought of a few of these. "Throughout Back To The Future Part III, there has to be two Deloreans in 1885. Also, why don't George and Lorraine recognize their son? Why doesn't the time machine disappear in the alternative 1985? These and more Back To The Future paradoxes explored..."
Er... you mean you DIDN'T notice that? I thought it was one of the more obvious things, put in to see if the audience was awake.
In fact, last month I showed my gf these films for the FIRST TIME EVER (she's authentic rural-Italian, and their cinema is wildly different to UK/US cinema so although they "know of" our movies, they have rarely actually gone to see them). She spotted that straight away, no hint of hesitation. In fact, just before any big "revelation" she was there pointing it out as the characters were about to introduce it into the main plot. Not to mention the various paradoxes here, she was working out where/how the movie had to go before it got there.
And she spotted the actress change for Jennifer. Most people don't unless they watch them one after the other.
The "lone pines" thing? Please, I would worry about how you keep track of ANY movie if you didn't spot that. You're like my mother, who can't watch Sliding Doors without getting confused.
Time travel is NOT possible. You can poo-poo all of the scientific theories you want, but you cannot be in two places at the same time.
