An actor who recently appeared in "Star Trek Into Darkness" is joining HBO’s fantasy drama series "Game of Thrones." The Hollywood Reporter’s Live Feed reports that "Thrones" has cast British actor Joseph Gatt.

Gatt recently appeared as a science officer in "Star Trek Into Darkness" and also played a frost giant in "Thor," the story notes.

While HBO isn’t revealing which part Gatt will play in the hit series, fans are speculating that he will play Styr, Magnar of Thenn, a wildling leader who has a hairless body. Because of the condition alopecia universalis, Gatt reportedly has no hair on his body.
