13. John Musgrave (Billy Crudup)

You can usually see a double cross coming a mile away in Mission: Impossible. Not when John Musgrave is silently mouthing instructions only a restrained Hunt can understand, and before he slips him a knife to set himself free. With Phillip Seymour Hoffman’s overwhelmingly dastardly performance as Owen Davian distracting us, and Laurence Fishburne’s ambiguously snarly depiction of IMF director Theodore Brassel misdirecting us, Crudup’s slick performance slipped his nefarious intentions through our detection like a snake in the grass. Without Crudup, Mission: Impossible III is predictably one-dimensional, and the outstanding torture scene fake-out with a captured Hunt and his wife Julia (Michelle Monaghan) has less of a punch. Musgrave is the logic behind the madness, and also an essential part of the film. He just isn’t as integral to the franchise as the 12 characters ahead of him.
