Actor Gerard Butler understands why the action thriller Law Abiding Citizen elicits such a strong reaction from the audience.  Playing Clyde, a man who goes on a bloody journey of destruction after his wife and daughter are murdered, Butler is at his scenery chewing best (think of Clyde as a combination of Hannibal Lecter and King Leonidas) with the film, which has made over $50 million at the domestic box-office.  Butler gives us his take on what makes Clyde such an interesting character.   (CLICK ON THE MEDIA BAR TO HEAR GERARD BUTLER)
