Johnny Knoxville, born Philip John Clapp, is an American stunt performer, actor, and producer who redefined physical comedy. As the co-creator and fearless leader of MTV’s Jackass, Knoxville achieved global notoriety by subjecting himself to outrageous, painful, and life-threatening stunts. Beyond reality television, he successfully transitioned into Hollywood, starring in box-office hits like The Dukes of Hazzard, Men in Black II, and the Oscar-nominated Bad Grandpa. After decades of enduring severe concussions, he retired from high-stakes stunts following Jackass Forever, shifting his focus to television hosting and producing scripted comedy.
