Sam Witwer Joins Supergirl as Agent Liberty 7/17/2018 2:00 pm

Comic Con starts tomorrow and just before we jump on a plane to head to San Diego, we've got BIG Supergirl news! Just as Batwoman was announced as "in-development" for her own show, Supergirl is announcing a new series regular for season 4! Sam Witwer (Smallville, Being Human, Once Upon A Time, Battlestar Galactica, Dexter) is joining the show as Agent Liberty! He is described as:

AGENT LIBERTY is the founder and figurehead of the Children of Liberty – a hate group that supports a human-first world order. Ruthless and terrifying, the scariest thing about Agent Liberty might be just how easily he can convince you that he’s in the right. He’s a brilliant orator in the guise of a family man.
