James Callis

Full Bio An actor who had plied his trade on the stage and screen for nearly a decade by the time he was cast as brilliant but traitorous Dr. Gaius Baltar on the hit sci-fi series Battlestar Galactica, James Callis displayed the pitch-perfect combination of swaggering arrogance and dangerous cowardice needed to betray the human race to its robotic oppressors. It was after studying English and literature at the University of York that the English-born actor enrolled in the prestigious London Academy of Music and Art, and after graduating in 1996, Callis quickly moved on the West End stage -- where he made his professional debut opposite Bob Hoskins in a production of Old Wicked Songs. Dubbed "Most Promising Newcomer" at the London Critic's Circle for his performance in that play, Callis subsequently appeared in an ~Almeida Theatre production of The Doctor's Dilemma and a ~Soho Theatre production of Things You Shouldn't Say Past Midnight.
