The two faces of Bradley Cooper

Bradley Cooper undergoes a daily transformation as he gets into character for the film The Dark Fields, which has been shooting around town the last two weeks and will be here till the end of May.

For many scenes, he's ratty-looking, with stringy hair pulled back into a ponytail. For others, his hair's looking all slick and he wears sports jackets.

Cooper hits hair and makeup for the one-hour session required to turn him scruffy.

On Thursday, he was neat when he met Mayor Nutter in the street between Hallahan Catholic High and Family Court. But shortly after, he shot a scene at the school's back door as his scruffier self.
