Some films by Alain Resnais deserve to be on this list: Je t'aime, je t'aime: a time machine experiment gone wrong. http://www.imdb.com/title/tt0063152/ http://www.imdb.com/title/tt0063152/ Providence: a story told while it's being written. Sometimes the writer changes his mind, sometimes his imagination takes him where he doesn't want to go. http://www.imdb.com/title/tt0076574/ http://www.imdb.com/title/tt0076574/ Smoking / No Smoking: two films that explore different possible 'forks' of the same story. The first fork is the decision by one character to smoke a cigarette. In the first film she does, in the second she doesn't. There are three or four forks in each film which all completely change the fate of the characters. http://www.imdb.com/title/tt0108167/ http://www.imdb.com/title/tt0108167/ Other films that come to mind: Code Unknown: Incomplete Tales of Several Journeys , by Michael Haneke. http://www.imdb.com/title/tt0216625/ http://www.imdb.com/title/tt0216625/ Akira has an ending just about as powerful as the ending of 2001. http://www.imdb.com/title/tt0094625/ http://www.imdb.com/title/tt0094625/ Beyond a reasonable doubt (Fritz Lang) http://www.imdb.com/title/tt0049006/ http://www.imdb.com/title/tt0049006/ (but why am I writing this on hacker news?) Vertigo (Hitchcock) http://www.imdb.com/title/tt0052357/ http://www.imdb.com/title/tt0052357/
