Pullman — who joins series stars John Barrowman, Eve Myles and the just-cast Mekhi Phifer — will play Oswald Jones, a dangerously clever convicted murderer who escapes his lifelong prison sentence on a technicality and quickly becomes a media sensation. Genuinely repentant yet boiling with lust and rage, Oswald gets caught up in a terrifying worldwide crisis.
Torchwood’s fourth season will air stateside on Starz in a co-production deal with BBC Worldwide Prods.
Pullman’s only major previous primetime gig was on NBC’s 2005 limited series Revelations.
