Who knew that it would take the infamous Gunpowder Plot to bring Game of Thrones and The Leftovers together? That’s the report on Kit Harington’s now-greenlit Gunpowder miniseries, as Liv Tyler and Sherlock star Mark Gatiss join the former Lord Commander in key roles.

Per Deadline, Harington is confirmed to both produce, and star in the Guy Fawkes BBC series, taking place over in three hour-long episodes. Harington will play the plot’s architect, Robert Catesby, a “30-year old Warwickshire gentleman and committed Catholic at a time when Protestant England persecuted the church’s members relentlessly,” and actual ancestor of Harington’s.

Fellow (albeit offscreen) Game of Thrones co-star Gatiss will play King James’ spymaster Robert Cecil, while Tyler plays “concerned Catesby cousin Anne Vaux.” Additionally, Top of the Lake star Peter Mullan plays the peacefully protesting head Jesuit Father Garnet. Here’s a brief synopsis:

Set in 1605, the historical drama is based around British radical Fawkes and a group of provincial English Catholics who attempted to blow up the House of Lords in UK Parliament and kill King James I in order to help restore a Catholic to the crown. The attempted plot, or Gunpowder Plot as its known, was foiled on November 5 when authorities at Westminster Palace found Fawkes guarding the explosives. To this day, Brits celebrate Guy Fawkes Night every year on November 5 with a fireworks display and by burning his effigy on a bonfire.

The series was developed by Ronan Bennett, Harington and Daniel West, with Bennett writing and J. Blakeson directing. Filming will start this month, so stay tuned for the latest.
