In Iron Man 2, Mickey Rourke plays the villain, Ivan Vanko. In several scenes, Vanko is seen to be a consummate hacker, typing away at the keyboard in a blizzard of keystrokes. Rourke's fingers look really fluid as he is doing this.
Is he just that fluid a typist, or did they speed up the action, use somebody else's hands or CGI maybe, to make it look as though he could type really fast?
It's sort of reminiscent of the banjo scene in Deliverance where they fake the boy's hands.
