I love science fiction, too. In high school I read comic books for escapism and today movies fill that role. I love time travel movies and discussing the paradoxes they offer. Some of my favorite movies are Star Wars, The Lord of the Rings, The Matrix, Back to the Future, The Avengers just to name a few.
Music: Led Zeppelin, Pink Floyd, Cake, Rob Zombie/White Zombie, NIN, KoRn, Disturbed, Alice in Chains, Filter, techno, 80's.
Books: novelizations of the movies listed above.
