Big time Space 2001 is a class film concerning sound, music, atmosphere, ect.
Blade runner too that film is techno and Assault on Precinct 13 (there doing a remake by the way)has some awsome synthy music.
Also horror films are a big thing to me return of the living dead has some top electronic music.Texas Chainsaw massacres overall vibe-filthy, dirty, glitchy, rotting, grimy,twisted, filthyfilthyfilthyfilthyfilthyfilthy err Im getting carried away now
