Memento and Inception, both by Chris Nolan
A Clockwork Orange

Definitely Pi and Memento. Good luck.

For realistic space-related stuff, "Contact" and "2001: A Space Odyssey" (both previously mentioned), "Apollo 13", "Gravity". The original "Planet of the Apes" is thought-provoking. Quite a number of "Nova" episodes are available on Netflix. For that matter, I don't suppose "Monty Python's Meaning of Life" or "Life of Brian" might be up his alley at all?

Gandhi?

Inherit the Wind?
