Most obituaries for Marcel Marceau mentioned his screen appearances in “Barbarella” and his famous cameo as the only speaking cast member of Mel Brooks’ “Silent Movie.” Utterly forgotten is Marceau’s only leading role in “Shanks,” a very strange little horror movie that was the last directorial credit of the legendary William Castle. Marceau plays a mute pupeeteer who is given a device that can animate dead bodies by a dying inventor (also Marceau) in this 1974 ultra-rarity from Paramount, which has never been released even on VHS in this country.
