Madhouse

Paul Toombes (Vincent Price) is a successful horror actor whose trademark role was Dr. Death, a skull-faced sadist. During a party in Hollywood, he announces his engagement to Ellen Mason (Julie Crosthwait), who gives him an engraved watch as an engagement gift. Later that evening, however, adult film producer Oliver Quayle (Robert Quarry) reveals Ellen Mason had worked for him previously. Ellen was killed by a masked man in dark garb, similar to Dr.Death's attire. Toombe is acquitted of the crime, but spends years in a mental hospital.
