A stand-out supporting player is Welles’ favorite Akim Tamiroff as Cagliostro’s trollish henchman. Of course, Tamiroff was wildly memorable in Welles’ TOUCH OF EVIL, THE TRIAL (1962 and DON QUIXOTE (1958). Tamiroff also worked with Welles collaborator Jess Franco in JUSTINE (aka DEADLY SANCTUARY/1969).
Actor/Director Ratoff directed around 30 films including THE CORSICAN BROTHERS (1941). Supposedly, veteran cinematographer Tonino Delli Colli (worked with Fellini, Leone & others!) was an uncredited camera operator.
Boris Karloff was originally announced to play the Count in a never realized Universal Picture in the 30’s that supposedly morphed into 1932’s THE MUMMY. Other actors to play the role include Jean Marais, Howard Vernon, Henry Daniell, Nicol Williamson and Christopher Walken, to name a few!
