In real life he's best known as an actor. People notice him as Kevin Costner. Apart, in the upcoming drama thriller you won't see him so, instead he'll change his role into a serial killer.
The movie entitled "Mr. Brooks," is about to be directed by Bruce A. Evans, who also wrote the script with Raynold Gideon. Shooting's scheduled for April 2006.
Anyway, that's only a matter of duty. In order to be noticed as a professional actor, Costner has to do that right?
