Considered to be the finest adaption of a comic book to date, Danger:Diabolik is to my my knowledge Bava's biggest budgeted film and looks it. The cast headed by John Philip Law as the suave super thief Diabolik and Marisa Mell as his beautiful girlfriend/accomplice Eva Kent do a superb job. There's also some strong supporting performances by Michel Piccoli as Diabolik's nemesis Inspector Ginko and Adolfo Celi as the degenerate crime lord Ralph Valmont here as well. On the technical side of things, Bava does his usual masterful job of directing. Pace is kept lively and never falters. The musical score was written by Ennio Morricone and is one of the best. I highly recommend this film.
