Mutt Williams, is portrayed by actor Shia LaBeouf in the movie Indiana Jones and the Kingdom of the Crystal Skull. He is the illegitimate son of Marion Ravenwood and Indiana Jones whom he joins on an epic adventure to return the fabled Crystal Skull to Akator. Mutt's persona is a motorcycle riding, knife wielding tough youth who finds that he has much to learn. During his meeting with Indiana a couple of spies watching them approached them demanding Indiana to hand over a letter. The threat triggered Mutt to pull out his switchblade, which was no match for the enemies guns. Later on in the movie, Mutt finds himself in a fencing match with Irina Spalko and holds his own.
