After murdering his wife, a young man finds himself in a lunatic asylum. Once inside he’s at the mercy of Dr Calahari, whose alternative treatment gives rise to a series of weird and nightmarish hallucinations.

Ken Russell’s fantastical, disturbing and whimsical “horror” film is inspired by a selection of Edgar Allen Poe’s stories, but is distinctly a Russell picture, complete with remote control gorillas and sex-doll orgies. This is a unique romp not easily forgotten.
