With Darth Vader's bloody backstory behind us, Young Hannibal: Behind the Mask, now shooting in Prague for '06 release, takes a stab at Hannibal Lecter's pre-Chianti salad days. Here, Gaspard Ulliel (A Very Long Engagement) plays out one of Lecter's early acts of violence, at a 1950s Lithuanian orphanage. ''What's the process by which a gifted child becomes a monster?'' asks director Peter Webber (Girl With a Pearl Earring), who promises ''nasty murders.'' As for collaborating with secretive author and virgin screenwriter Thomas Harris, Webber laughs. ''If I told you, I'd have to kill you!'' And then eat you.
