You may know Mark Gatiss from his behind the scenes work on Doctor Who as novel writer and episode scribe. You may even recognize him as Mycroft from the BBC’s Sherlock. Whether you know his work or not, we’re more than confident to say that his new television endeavor will only benefit from his presence.

According to Entertainment Weekly, Mark Gatiss is the latest cast member for Season Four of Game of Thrones. There’s no word as to who he will be playing but he’s phenomenal on Sherlock. I cannot wait to see him in Game of Thrones.

Game of Thrones stars Peter Dinklage, Emilia Clarke, Lena Headey, Kit Harington, Jack Gleeson, Natalie Dormer, Nikolaj Coster-Waldau, Charles Dance, Sophie Turner, and Maisie Williams, airs on HBO.
