Is 'Barry' a psychopath? We asked Bill Hader

Bill Hader doesn't really know what's wrong with Barry Berkman, the assassin turned aspiring actor he plays on HBO's hit show, "Barry."

The series, created by Hader and writer Alec Berg, is an odd concept. Hader plays Barry, an ex-Marine and hitman from Cleveland who heads to Los Angeles for a kill. Instead, he finds himself joining and really liking an acting class taught by Gene Cousineau, played by Henry Winkler. The problem is, he's still killing people due to various circumstances.

Hader rides the line between being a stone-cold killer of strangers, friends and friends of friends, but then is able to access emotions in the acting class and finds himself falling in love.
