David Copperfield REFUSES to accept responsibility for serious injury to tourist who slipped during an illusion as lawsuit reveals the secrets of his signature MGM Grand trick

David Copperfield, appearing in court in Las Vegas (top left), didn't acknowledge responsibility for injuries British man Gavin Cox (bottom left) claims to have suffered when he fell during the illusion (right) in 2013. But the celebrated magician did say it might be his fault if an audience volunteer who was participating in a trick got hurt. Cox, from Kent, claims lasting brain and body injuries and more than $400,000 in medical expenses. The court has heard how practiced stagehands with flashlights hurried randomly chosen participants through dark curtains, down unfamiliar passageways, around corners, outdoors, indoors and through an MGM Grand resort kitchen in time to re-enter the back of the theater for their 'reappearance' during the show finale.
