Victor Garber has been cast as Dr. Martin Stein - the other half of Firestorm.
The character has been described as “a brilliant but arrogant nuclear physicist who has sacrificed everything, including a marriage, for his work in transmutation. After he discovers the particle accelerator has fused him with the younger, more impulsive Ronnie Raymond (Robbie Amell), he races to find a way to separate the two before it’s too late.”
It was reported back in July, that Robbie Amell will play the role of Ronnie Raymond, a maintenance worker at S.T.A.R. Labs and Dr. Caitlin Snow's (Danielle Panabaker) fiancé.
Dr. Martin Stein (Garber) will first appear in the 12th episode of The Flash and recur through the rest of Season 1, while Ronnie Raymond will make his debut in the series' third episode.
Garber is best known for his role in Alias, playing Sydney Bristow’s dad, Jack, and also starred in James Cameron's Titanic.
The Flash airs Tuesdays on The CW.
