I'm not a doctor - so I can't describe flashbacks well - but it is like you're living it again.
This was basically the first time I got to act in action scenes, with things blowing up all around me. It sounds corny, but I think every actor would like to - at least once in his or her career - play the person who saves the entire world.
No critic writing about a film could say more than the film itself, although they do their best to make us think the oppposite.
