Actor Kit Harington is reuniting with his Game Of Thrones co-star Carice Van Houten for the upcoming thriller Brimstone after stepping in to replace fellow Brit Robert Pattinson.

The Twilight star had been attached to headline the movie with Aussie Mia Wasikowska when the project was announced at the Berlin Film Festival in February, but they have both since quit the film.

Pattinson's fellow Twilight franchise star Dakota Fanning was cast as Wasikowska's replacement, and now Harington, whose Game of Thrones character was killed off in the recent season five finale, has been tapped to take on the actor's outlaw character.

Aussie actor Guy Pearce also stars as a villainous Preacher, who attempts to hunt down Fanning's character Liz, while Van Houten (Melisandre in Game Of Thrones), Sherlock Holmes: A Game of Shadows' Paul Anderson, Jack Roth and Carla Juri round out the cast.

Martin Koolhoven is directing the movie from his own script.

Production is currently underway, ahead of a planned 2016 release.
