Monsieur Brooks

Well-respected businessman Earl Brooks (Kevin Costner) has a secret: Beneath his family-man facade lurks a murderous alter-ego named Marshall (William Hurt) . Brooks struggles with his addiction to killing, but Marshall enjoys his grisly hobby too much to let go. Finally, Brooks resolves to commit one final murder, but a voyeur (Dane Cook) witnesses it and blackmails him to continue. With a detective (Demi Moore) hot on his trail, Brooks/Marshall must spin an increasingly elaborate web.
