While Game of Thrones star Kit Harington was poised to get his first feature film starring role with Arthur & Lancelot, Warner Bros. abruptly put the David Dobkin-helmed project on hold in order to sort out the swelling budget. The film isn’t yet dead, but production has been pushed back leaving a hole in Harington’s schedule. It appears the actor was quick to fill that void, as Variety reports that he’s now in final negotiations to join the cast of The Seventh Son. The film stars Jeff Bridges as a grizzled witch hunter who takes on a new apprentice in the form of Ben Barnes. Harington will play a former apprentice of Bridges’ character in the fantasy pic.What this means for Arthur & Lancelot is uncertain. Harington is due back on the Game of Thrones set after he wraps The Seventh Son in order to film the third season of the hit HBO series. This means he likely won’t be available until fall at the earliest (season two of GoT filmed from July to December). Depending on when/if WB starts Arthur & Lancelot back up again, Harington may find himself replaced. No matter, he’s one of the highlights of Game of Thrones and as evidenced by how quickly he found a replacement project, he’s definitely got a bright feature career ahead of him.
