The new release date is three days before my 21st birthday! I could not be any happier (unless the movie sucks... then I'm just going to get hammered and try to forget).
I know it's highly unlikely (basically impossible), but how cool would it be James Cameron returned for Alien 5? I think his Avatar sequels would have to fail pretty hard, but with every delay that befalls them, I feel like it becomes a stronger possibility, even though it probably won't happen. *random thought*
