Westeros could end up on the big screen with news that a Game of Thrones feature film is being developed by Warner Bros.

The project is still in its early stages, with no filmmaker, cast or writer yet attached.

This isn’t the first time the franchise has flirted with a cinematic release. The showrunners of the original Game of Thrones series, David Benioff and Dan Weiss, famously wanted to finish the series with a feature film trilogy instead of its divisive season 8. Author George R.R. Martin was reportedly also supportive of the idea. At the time, however, HBO resisted the idea in order to retain the prestige series as an HBO property.

HBO’s attitudes have shifted since then, with several properties hopping from the big screen to the small screen and vice versa. Matt Reeves’ The Batman, for instance, moved to HBO with the spinoff series The Penguin, and Max will be getting Dune: Prophecy as a spinoff from Denis Villeneuve’s Dune films. HBO is also preparing a television adaptation of the Harry Potter novels. By those standards, it’s unsurprising that HBO would now be more accepting of Game of Thrones making a move.

The project is, however, still in early development, so nothing is set in stone. Stay tuned for updates.
