The actor previously starred alongside "GOT" Season 2 cast member Tom Wlaschiha (Jaqen H'ghar) in the film, "Resistance" in 2011.

He also appeared in the British television series "Misfits," which featured Michelle Fairley (Catelyn) in a small role as a mother of one of the misfits.

Speculation that the actor had joined the cast of the show first emerged earlier this month when he was spotted at Belfast's Laverys bar. Iwan was pictured alongside Alfie Allen (Theon Greyjoy), Gwendoline Christie (Brienne) and Nikolaj Coster-Waldau (Jaime Lannister) playing pool.
