True Blood's Michael Raymond-James Joins Once Upon a Time

True Bloodalum Michael Raymond-James has landed a recurring role on the upcoming second season of Once Upon a Time, TVGuide.com has confirmed.
Details about his part, which was first reported by Entertainment Weekly, are being kept under wraps, with reps for the ABC series calling his role a "mysterious new character."
