Madhouse

Aroview: British horror film based on the 1969 novel Devilday by Angus Hall, with Vincent Price playing a horror actor renowned for his character Dr. Death, who may have trouble getting out of character.

After spending 12 years recovering in a mental hospital following his fiance's murder, which he was acquitted of, he returns to the acting world, and bodies start piling up. A decent vehicle for horror icon Vincent Price, entertainingly set in the horror film industry itself.
