Sam Witwer Joins SUPERGIRL Season 4 in Series Regular Role

Casting is underway for new characters on The CW’s Arrowverse, including Supergirl. Today, the show (which is entering its fourth season) has added a major new player to the cast.

It has been announced that Sam Witwer has joined the cast of Supergirl as a series regular for this season. (Shout out to Discussing Film for breaking the news earlier.) He will play Agent Liberty, who is described as “…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.”

It definitely sounds like Agent Liberty will be an antagonist of sorts for Kara and the team. However, it’s unclear if he will be the actual big bad of this season.

Witwer has plenty of geek cred in his career. He was on The CW’s Smallville as Davis Bloome, the human alter ego of Doomsday. He also voiced Ocean Master in the animated movie Justice League: Throne of Atlantis. But most significantly, Witwer has taken the voice role of Darth Maul in Star Wars: The Clone Wars, Star Wars Rebels, and Solo: A Star Wars Story.

We’ll learn more about the latest season of Supergirl this season at San Diego Comic-Con. Stay tuned.
