If you were going to be a star in the next big movie, what kind of character would you be? What would happen in the movie?

Well based on my personality I would be the mellow or chill kind of guy. But when I would make to whatever goal is needed and make it count. But now as I think of it it would be really sick if I played a role where the character has a split personality. One side a sane, calm, logical, sensitive guy where he stand up for the little guy. On the other side is a psychotic genius, master of firearms and martial arts, and is hired to kill. 

What would happen in the movie is that the kind one would start to make friends at school and all. Then the kind one would start to notice how is he getting money that is dropped off by men in black. This happens frequently in the alley way behind his house. So what he starts doing is starting to set up security systems around his house. Then he awoke one night to find him self cut and brused and a few bullet wounds in his leg. His parents take him to the hospital and yada yada. He finds out he has a split personality, and his friends wonders where he goes after school and during school as he becomes more consumed by this other side. Then the good side doesn't want this no more so he struggles with it and fights it. But when his friends and the love of his life is in danger, he has to choose to give in to the psychotic one to save his friends or his sanity.
