Xah Favorite Hard SciFi Movies
Coherence
the whole movie happens inside a room, basically. This movies, but, stir up fear more than any explicit ghost or monster or killer movie.
2001: A Space Odyssey Buy at amazon • A realistic rendering of the year 2001. A outline of the history of human animals.
Apollo 13 Buy at amazon • Nice normal american heroic happy-ending movie.
Gravity scifi 97%. Excellent.
