This movie has instantly become one of my very favorite Mario Bava features. Think James Bond, as a suave master thief, filmed in a psychedelic, occasionally campy, comic book style. (Diabolik was a comic first.) Add to that some fun humor and very fitting themes by the legendary Ennio Morricone, and you have one cool, little cult flick! The cheap DVD comes with some great extras, like a pleasant and informative commentary by star John Phillip Law and Bava expert Time Lucas. The short featurette was very good too, going over just how well Bava captured the comic book stylings in the film. Recommended purchase! By the way, Diabolik's mask and laugh---perfect.
