“Somebody find me a carrot stick.” So said millions of moviegoers upon exiting screenings of Super Size Me, documentarian Morgan Spurlock’s gonzo 2004 sensation. Spurlock’s film, based on a stomach-churning conceit, tested the limits of the director’s physical, psychological, and (not least) spiritual courage. For 30 days, with cameras capturing every greasy belch and sigh, the filmmaker consumed nothing but McDonald’s. If the iconic movie poster of the 1970s was Roger Kastel’s terrifying work for Jaws, the aughts equivalent may well have been Spurlock staring fearfully at passersby, his open mouth stuffed with fries.
