EXCLUSIVE: It’s official. Emilia Clarke will play Sarah Connor in the Terminator reboot, re-teaming with director Alan Taylor, who has worked with Clarke in the HBO series Game Of Thrones. Clarke joins Jason Clarke, who is in negotiations to play her son John Connor in a storyline I’ve heard involved a trip into the future. Deadline revealed that he was in talks earlier this week. Arnold Schwarzenegger is also back in his signature cyborg role.

This was a hotly contested role and it came down to Clarke and Brie Larson. Both actresses tested for the producers at David Ellison’s Skydance and Megan Ellison’s Annapurna, and Paramount, which will release the film in July 2015. Clarke’s breakout role came in Thrones, where she plays the dragon-commanding heroine Daenerys Targaryen in that massive HBO series, and is probably the most sympathetic of all vying to rule. She started as a shy sister of an annoying king brother, but has demonstrated the mettle to capably play one of the screen’s most formidable heroines as originated by Linda Hamilton in James Cameron’s first two films in the series. She’s repped by CAA and Emptage Hallett in the UK.
