Far too many to mention, and so instead of re-list things anything already posted I'd add - Predator 2, Silent Running, The Black Hole, A Boy and His Dog, Dark Star, Total Recall (first version), Invasion of the Body Snatches (all versions), Repo Man, The Hidden, John Carpenter's The Thing and They Live.
Millions more of course but that's a start at a contribution.
