Was The Help too girly of a "white star does accent to help black people" story for you? Well, here's one with Gerard Butler, and rocket launchers. Plus, it's based on a true story, so that means it washes away twice as much white guilt.
When it comes to shouting in a completely inexplicable accent, Gerard Butler is the best. Please, no one ever show him one of his movies. Let's keep this "American" voice pure.
