This is a clip from the upcoming movie Kick-Ass. Staring Aaron Johnson, Nicolas Cage and that kid from superbad, Christopher Mintz.
Dave Lizewski is an unnoticed high school student and comic book fan with a few friends and who lives alone with his father. His life is not very difficult and his personal trials not that overwhelming. However, one day he makes the simple decision to become a super-hero even though he has no powers or training.
Looks like It’s not going to be a very good movie, but not very bad one, either.
