Mutt Williams (Shia LaBeouf) - Indiana Jones and the Kingdom of the Crystal Skull (2008)
Okay so 'The Beef' could've made it into this list for just about any movie that audiences have had the misfortune of seeing him in. But it's his turn as Mutt Williams, the ill-advised addition to the Jones family in 2008's disastrous three-quel that really gets our blood boiling.
Never mind nuking the fridge, messrs Spielberg and Lucas declared full on thermo-nuclear war by including the preening pubescent in the iconic film franchise. Lets overlook for a second the stupid haircut, ridiculous wardrobe choice and 'that' infamous tree-swinging scene, and instead focus on the gurning greaser's constant quarrelling with Indy himself. How precocious can you get? After all, Indy has been dodging giant boulders since before Mutt was even a twinkle in his mother's eye, which is something else the fedora-topped explorer knows a thing or two about as well.
