Suddenly my brain is filled with memories of great, great movies...
Shape-shifting horrors:

www.galaxy-of-terror.com , except to females...)
-Forbidden World
Food for thought:
-Soylent Green
-Zardoz
-Silent Running
-Brainstorm
-The Man Who Fell To Earth
-Dark Star
-Gattaca
Madness:
-Star Crash
-Ice-pirates (space-herpes FTW)
-Knights (there are goddamn VAMPIRE ROBOTS in this!)
-Destroy All Monsters
-Dünyayi kurtaran adam ("Turkish Star Wars")
-Starship Invasions (loads of immortal dialogue. "We need a human female")
Post-apocalypse:
-Mad Max II & III
-A Boy And His Dog
-2019 - After the Fall of New York (if that's not the coolest title ever...)
Other:
-Tetsuo I-II

-Total Recall
-Hardware
-Barbarella
-Dune (a guilty pleasure)
-The Last Starfighter
-Acción Mutante
-Cube
-Avalon
-the Ghost in the Shell movies

-The Contenders, Series 7
-Battle Royale
-Turkey Shoot
