William Castle was Hollywood’s undisputed “King of Gimmicks,” who gave us “Emergo,” “Percepto,” “Illusion-o,” “The Coward’s Corner” and “The Fright Break.” Early in his career, he worked as an associate producer for legendary filmmaker Orson Welles. Castle gained a reputation for his unorthodox promotional techniques and his ability to bring film production in under budget.
Castle passed away in 1977, but, based on his memoirs (published in 2010), I’m not so sure.
