Four more people have been cast for Season 2 of Game of Thrones. Irish actor Michael McElhatton will play Roose Bolton, Welsh actor Robert Pugh will play Craster, Ben Crompton will play Dolorous Edd, and Karl Davies will play a new character named Alton Lannister. The addition of Alton is likely being done in order to scrunch a few characters together so producers can contain the universe and keep casting down.
