Somehow, Us got ahold of the behind-the-scenes footage from Michael Jackson's 1984 Pepsi commercial, where a pyrotechnic accident lit Jackson's head on fire and caused the singer second and third-degree burns. This isn't some faraway raw footage, either -- it's a close, artfully edited video with background music, liberal use of slow-motion, a black-and-white Us Weekly logo, and a man's head on fire. Us alleges that the incident kickstarted Jackson's prescription drug habit; I can certainly attest that the existence of the video induces extreme queasiness. [Us]
