Beast In The Cellar, The (1971)

aka’s: The Cellar/Are You Dying, Young Man?/Young Man, I Think You’re Dying

When viciously mutilated bodies begin turning up on a remote British moor, local police blame the grisly killings on some powerful, unknown carnivore. What they don’t know is what sweet old Ellie and Joyce (Beryl Reid and Flora Robson) have been keeping bricked-up in their dark basement for the past thirty years.
