The Story of Big Brother Magazine charts the rise and fall of the irreverent, boundary-pushing Big Brother Magazine, whose taboo-breaking stunts and unapologetically crass humor spawned MTV’s Jackass and a generation of skaters. Featuring a trove of original footage and interviews with the magazine’s major players, “Dumb” celebrates the lowbrow legacy of this touchstone of 90’s counterculture. With Spike Jonze, Johnny Knoxville, Steve Rocco, Bam Margera, Steve-O, Tony Hawk, Chad Muska.
