A wonderfully funny take-off on "Faust", with Peter Cook as an affable, more than generous Devil, giving poor Dudley Moore every opportunity to find happiness, only to thwart him each time. This film is full of wickedly satirical episodes - Peter Cook even manages to get away with cheating and insulting a sweet little old lady, and his portrayal of a rock idol who can arouse hysteria among girl fans with his aloof demeanour and song lyrics ("You fill me with inertia!") is incredibly funny. This is a great British comedy from the 60s, before filmmakers became too timid to try real satire anymore.
