SEASON PREMIERE: All the principals are back for this new season, but not all at once. Tonight’s season premiere, for example, is all about Hannibal’s relocation abroad, with his former therapist, played by Gillian Anderson, in tow. Also along for the ride: Hannibal’s unlucky captive, played by Eddie Izzard, whose part gets a little smaller each week – at least in terms of net body weight.
