Madhouse 1974

Paul Toombes made himself a Hollywood star by playing the role of Dr. Death in a series of successful horror films written by his friend, Herbert Flay. But now, after years in a mental institution following the murder of his fiancee, Ellen - a murder that many, and even he himself, believe he committed - he wants nothing to do with the homicidal character. Herbert, who is writing a new TV series about Dr. Death, persuades him to return to the role. Paul soon regrets the decision when the producer of the series turns out to be the former maker of porn movies in which Ellen starred. Worse, his new female lead is arrogant and incompetent. Meanwhile, he discovers that he is not the only guest in Herbert's home. There's also Faye, his former co-star, who has gone mad after being deformed in a car explosion. But none of this unpleasantness compares to the horror of Dr. Death himself. It seems the character has a will of his own - a will to commit murder.
