No list of angsty celebrities would be complete without Hollywood's biggest hothead. We've all heard the tapes, and we can all agree: Mel is a very angry person. Who needs a "Lethal Weapon" when you've got Mel's killer glare? He's turned his icy gaze on everyone and everything from John Lennon to Jews to his baby mama to dinnertime. We're not quite sure what the source of Mel's angst is, but if he's trying to live up to the Mad Max name, he's doing a mighty fine job! Hooray!
