After Welles's return he and Cotten co-produced "The Mercury Wonder Show" for members of the U.S. armed services. Opening August 3, 1943, the all-star magic and variety show was presented in a tent at 9000 Cahuenga Boulevard in Hollywood. Featured were Welles (Orson the Magnificent), Cotten (Jo-Jo the Great), Rita Hayworth (forced to quit by Columbia Pictures boss Harry Cohn and replaced by Marlene Dietrich), Agnes Moorehead (Calliope Aggie) and others. Tickets were free to servicemen, and more than 48,000 of them had seen show by September 1943.
