Smart people make good choices. They dig science and say 'no' to the invasion of sovereign nations for the pleasure of corporations.
If it were a choice between me getting killed or one of my friend's kids, I would happily take the shot.
I don't get a lot of choices in movies. It's not like I'm Brad Pitt and I can walk in and go here's the film I want to do and everyone runs around... I don't have that. I stand in line and do auditions. I'm there with 80 other guys trying to be that guy. Every once in awhile I luck out.
