Supergirl Season 4
Welcome to Supergirl, Sam Witwer.
Sounds like you’re a season 4 Big Bad — as Agent Liberty, the founder and head of hate group Children of Liberty 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. — Warner Bros. Television.
Supergirl filmed several sequences with Sam Witwer in downtown Vancouver’s Harbour Green Park for what is thought to be episode 4×03 Man of Steel: starting the day with him running with others in the park from some kind of threat. Alien threat?
Then with a stretch limousine where he’s walking down the street and stops to talk with Mercy Graves (Rhona Mitra), Lex Luthor’s former bodyguard and fellow anti-alien activist.
Who’s inside? Mercy Graves (Rhona Mitra).
