I made a collage of movie soundtrack songs that I've always liked, and layered samples from film and television on top of that. I tried to choose soundtracks that had a nice ambient feeling and that blended well together when played together. I chose the audio samples based on the tone they seemed to have, and also tried to mix some silliness into the seriousness of the soundtrack sounds.

The soundtracks:
Dune (Toto rules!)
Blade Runner
Nadja (movie is not so good but the soundtrack is fantastic)
Twin Peaks
Wild At Heart

The audio samples:
Panic in Year Zero
He-Man
Star Trek Voyager
Doctor Who
I Married a Monster from Outer Space
Zoolander
The Muppets
