Jamie Foxx and Gerard Butler have a lot of practice with their "stern" faces, whether it's fighting for the glory of Sparta or pretending to be a blind, struggling pianist. Those hard glares are getting lots of practice on the final poster for Law-Abiding Citizen, which combines two early teaser posters into one combo-pack of watch-your-mouth.

The movie, which comes out October 16, finds Butler as a man who kills the murderer of his wife and child, and then promises a young prosecutor that he'll kill everyone else who helped the murderer get off with a light sentence 10 years ago unless the justice system is completely overhauled. Well, that's one way of effecting change in the government. Check out the poster below.
