Films: Anything by Darren Aronofski, Coen Brothers, Chris Nolan, also, schlocky horror, think-y sci-fi (Cube/Dark City), Princess Bride, and I'm generally a sucker for any high school stuff (Election, Heathers, Mean Girls, no HS musicals though!)
TV: Usual HBO - Sopranos, Six Feet, Game of Thrones, The Wire, also BSG, Buffy and West Wing.
Books: Paul Auster, Thomas Pynchon, Lovecraft, James Joyce, and comics too.
Music: Mainly rock, though not too fussy. Love Death Disco in Glasgow, and used to go to Optimo loads, so whole rock/electro thing is good. Occassional pop song gets stuck in my head from time to time too.
