I love sports. When I'm not playing, I'm watching, reading, or otherwise obsessing about them. This probably stems from growing up in Indiana, where if you didn't at least attempt to play basketball, you were considered of dubious moral character.
'Twilight' was about a naive person who knew nothing of a certain world, basically discovering that this world existed and totally being indoctrinated into it and falling in love with a vampire, which is interesting.
I can tell you that from the director's chair, young actors love to be challenged, to be given killer lines that take time to wrap their mind around.
