Whether or not Cersei Lannister ends up ruling on Game Of Thrones, the woman who plays her is already looking for her own new job. Lena Headey 's joining Karen Gillan in Gunpowder Milkshake . Aharon Keshales and Navot Papushado will co-direct the movie, working from a script they co-wrote with Ehud Lavski. While the story is mostly still being kept under wraps, it'll chronicle hired killers, following multiple generations with Gillan as the cornerstone of the plot. Deadline's report offers no details as to what Headey will be doing in the film, but we're hoping for badassery. Shooting on this one should kick off this spring in Berlin, while Headey will next be seen on the big screen in wrestling biopic Fighting With My Family, due on the 27th of this month. That's followed by the much-anticipated return of Thrones for its final season, and you can find out more about that right here. Discuss this with fellow SJF fans on Facebook .
