Duncan Lacroix, 'Murtagh'
Duncan Lacroix ("Game of Thrones," "Primeval") will play Murtagh Fitzgibbons Fraser.
Murtagh, Jamie's godfather, is a taciturn man, but very loyal to Jamie. Mysterious and dark, like a vulture lurking in the background. Murtagh doesn't say a lot, he doesn't have to; his reputation, and if need be, his fists, do the talking. At first skeptical of Claire, like his fellow clansmen, Murtagh eventually warms to her - whatever is best for Jamie.
