One thing PKD did that lends itself to moviemaking is just the fact that his novels are generally short and focus on quickly building a fantastic yet consistent world in the first few pages. Then he gives us a plotline that involves a conflict between the world he's built for us, and our common sense notions borne out of our experience in the "real" world. The cherry on top is the denouement, where he asks us: are you sure your world is the "real" one? I think this formula just really matches the pace and scope of a feature-length movie. Note that TV series based on his books have not been as numerous or successful. The best of the bunch may be "Man In The High Tower", but it massively diverges from the book not too far in. Also, he was a f*king genius at predicting future memes.
