Super hard to limit to just 5 but here's the first that came to mind: Star Wars: A New Hope, The Matrix, Delicatessen, The Science of Sleep, The Fifth Element.

Any of the following could easily go somewhere on the above list :) Blade Runner, 12 Monkeys, 2001: A Space Odyssey, Brazil, The Hudsucker Proxy, Groundhog Day, Dark City, Inception & Intersteller (if only it didn't have the whole love is a force that transcends dimensions and can be used to communicate across time and space stuff?!)
