Total Recall (1990) was loosely based on a Philip K. Dick story, and a darn good film. It's been awhile since I last saw it. Another film to add, also based on a Philip K. Dick novel is Blade Runner (1982) with Harrison Ford opposite Rutger Hauer.

And in the '90s, Galaxy Quest (1999) with Tim Allan and Sigourney Weaver, a blast to watch.
