S1 / Ep4 - James Cosmo

Todays guest is the wonderful actor James Cosmo. He's played everything from Santa Claus in Narnia to Ewan McGregor's dad in Trainspotting. Along the way he's killed hundreds of people with swords, guns and his fists. Oh, and he was also in a little show called Game of Thrones as the beloved Lord Commander of the Night's Watch.
