I am a massive Star Wars and Star Trek fan much to my friends amusement. They think I am particularly sad in that I know which bits of the Star Wars films episodes IV to VI had been added when they were digitally enhanced in the 90s.
With regard to books I can highly recomment the Philip Pullman Dark Materials Trilogy. They were mentioned a few threads ago (The Amber Spyglass, The Subtle Knife and The Golden Compass).
Also an author called Terry Prachet and his discworld books. They are funny, my favourite one is called Mort. It's about Death and how he gets tired of his job and so looks for an apprentice.
Also I am a big Harry Potter fan. I prefer the books to the films because I don't think anything can beat your own imagination.
