Cogman's name may not be immediately familiar, but if you're a fan, he's likely written some episodes that you've loved, such as this season's "The Laws of Gods and Men," which had Tyrion Lannister up on trial. Cogman's been around since the very first season of the Game of Thrones. Though he isn't one of its primary writers, he's been present each season, including for two episodes of Season 4.

Though work has started on Magic, an actual film is still a ways out. This is only a first draft, there's no director attached, and there's no sign that Fox is rushing to get this on screen. Still, a fantasy movie from a Game of Thrones writer is an obviously appealing prospect. The only other details for now is that Simon Kinberg, who's written and produced several X-Men movies, is on board to produce.
