Heath Ledger steeped himself so deeply in the role of The Dark Knight’s Joker that he said it became a highly disturbing experience for him; the ultimate toll it took on the late actor may never be known. On the bright side, however, you can make yourself look like the Joker and all you need is an iPhone. Forget about all that painful Method acting, just get the Apple application, snap yourself—or anyone, for that matter—and enjoy applying the make-up of, as the late Mr. Ledger described his character to the New York Times, a “psychopathic, mass murdering, schizophrenic clown with zero empathy.” Fun, eh?
