Hmm, earthbound spacesuits (maybe?) causing paranoia.... that narrows it down to just about every scifi film of the 50s!
Don't forget to include just about half of those from the 60s, 70s, 80s, 90s, and now!
And on an unrelated note: I've been reading about some upcoming SciFi films, and Ridley Scott wants to turn one of my alltime fav books into a movie - Joe Haldeman's Forever Wars!! I just hope the movie is made closer to the book than my most dissappointing fav book made yet, Starship Troopers. Apparently JMS wants to remake Forbidden Planet... it'll be hard to top.
