Gerard Butler: Mullet Man

Getting into character, Gerard Butler was spotted on the set of his new movie “Machine Gun Preacher” on Monday (July 12).

The “P.S. I Love You” stud donned a mullet wig and some trashy duds as he filmed scenes in a Detroit, Michigan trailer park.

“Machine Gun Preacher” is the story of Sam Childers, a former drug-dealing biker tough guy who found God and became a crusader for hundreds of Sudanese children who've been forced to become soldiers.

Due to hit theaters in September of 2011, the film also stars Michelle Monaghan and Michael Shannon.
