The cast of Game of Thrones’ sixth season continues to grow, with Richard E. Grant now joining the HBO series in a currently undisclosed role. His talent agency initially added the show to his online resume before quickly removing it. However, it appears as if the British actor is set to show up in multiple episodes, so his role could end up being a leading one.

Grant has recently been seeing in everything from Downton Abbey to Doctor Who and Girls.

He’s among a number of British actors to have recently joined Game of Thrones, with other notable additions including Jonathan Pryce and Ian McShane. Also set to star in the series next year are Freddie Stroma, Pilou Asbæk and Max von Sydow as the Three-Eyed Raven.

Season six of Game of Thrones (which will premiere April 2016) is the most exciting yet because the TV series has now overtaken the books. That means no one is quite sure what to expect, hence why there’s been so much speculation about the future of Jon Snow.
