I only saw the play version of Frost/Nixon, and I'm hesitant to go see the movie because the play was just...wonderfully captivating and thought provoking (I thought ti was very well done too, but I'm not a big theater-scene person, so my opinion prob'ly isn't worth much) and I'm afraid the movie won't live up to what I expect.
I'm the type of person who, every time I hear a rumor that someone is making a movie of Ender's Game, I cringe.
I'm sure someone's already suggested the Terry Pratchett Discworld books, because they're really just that fantastic. I'd also say try the Dresden Files by Jim Butcher, they are excellently done, sort of a fantasy-meets-modern-life thing, but without all the sex and sadomasochism that the Anita Blake series by Laurell K Hamillton has. I haven't read Butcher's other series, the Codex Alera, but I hear it's good if you're into the 'fantasy-epic-quest-kingdom-adventure' sort of thing.
I'd also say the Life of Pi, by Yann Martel. I read it in I think 5th grade, and I re-read it every year, because it's one of those books that you always see new things, or learn something from, when you go back over it.
I haven't got much on movies, I'm not really a movie sort of person. Seven Pounds was a good movie, although I found parts of it just too convenient to be believable. Other good ones are the Fifth Element, and I liked Death Race (it has that british actor, whose name I can't remember...). More action movie than i really like, but it was fun to watch.
