| A big big big classic : "2001: A Space Odyssey" by Stanley Kubrick.
This movie is amazing, there are a lof a cultural reference, and the final scene with the robot Hal 9000 is so good ! (and there are similarities in "wall-e" I'll speak about it later)
It speaks about the evution of humanity, artificial itelligence and space flight
The soundtrack is well-known too : Also sprach Zarathustra (Strauss), try to listen to it, you will certainely recognize it :D
