My absolute favorite is Coil, but I also listen to a lot of Mogwai, Cure, Autechre, Flaming Lips, Arvo Part, Julian Cope, Nick Cave and The Bad Seeds, TV on the Radio, Kronos Quartet, Queens of the Stone Age and Arcade Fire.
Movies
#1 Favorite: The Fountain. I quite like Star Wars, and by Star Wars I mean all of them and especially the prequels. I've recently rediscovered The Matrix Trilogy as well (especially Revolutions). Blade Runner, Donnie Darko - The Directors Cut. Past that, I like Darren Aronofsky, Luis Buñuel, some Federico Fellini, Peter Greenaway, David Lynch, Martin Scorsese, and Wim Wenders.

30 Rock, The Colbert Report, The Daily Show, Futurama, The Office, Scrubs, Seinfeld and The Simpsons.
Books
William S. Burroughs, Brian Greene, Steven Hawking, Henry Miller, Salman Rushdie, Carl Sagan, Kurt Vonnegut.
Heroes
William S. Burroughs, Joseph Campbell, Marcel Duchamp, Egon Schiele, Joel-Peter Witkin... Basically anyone who has either designed a world or destroyed one. Also the brothers, John and Thomas Knoll.
