Game of Thrones may have ended its seventh season last night (August 27), but Kit Harington fans won't have to wait long before he's back on our screens.

He's due to star in Gunpowder, a new three-part drama about the 1605 Gunpowder Plot due to air in the U.K. this fall, and the BBC just released photos and a short promo video with the caption "Autumn is coming."

Kit doesn't actually play Guy Fawkes, the man most readily associated with the plot to kill the king by blowing up London's Houses of Parliament, thanks to the rather dubious annual British tradition of setting off fireworks and burning a stuffed effigy (called a "guy") to celebrate the foiling of the plot.

As central as Fawkes is to the story of the plot, he is not the star of this particular telling of history. Kit will instead take on the role of Robert Catesby, the 30-year-old Warwickshire gentleman, who's often referred to as the "mastermind" behind the failed plot.

Sure enough, the 30-second teaser follows a trail of gunpowder into a cellar where Fawkes (Downton Abbey's Tom Cullen) sits in wait, before turning to reveal Kit-as-Catesby behind him:

Autumn is coming...

Gunpowder explores the real-life events behind the plot, following both the plotters and Robert Cecil (played by Sherlock's Mark Gatiss), the spymaster-in-chief of King James I (Derek Riddell).

Lord of the Rings star Liv Tyler also stars as Catesby's cousin Lady Anne Vaux, who also became embroiled in the plot.

Here she is with Kit, while Wolf Hall actor Edward Holcroft looks on as Catesby's friend and co-plotter Thomas Wintour.

And rounding out the cast are Happy Valley's Robert Emms as Father Gerard, a firebrand young priest; Broadchurch's Shaun Dooley as Sir William Wade, Lieutenant of The Tower and Robert Cecil's right-hand man; with some possible light relief in the form of comic actors David Bamber as the Earl of Northumberland and Kevin Eldon as Sir Joseph Hawksworth.

So far all we know is that it's due to broadcast in the U.K. in the "autumn," and we're willing to bet that might mean an air date close to November 5 (a.k.a. Guy Fawkes Night). We'll let you know when a U.S. airdate is announced.

Are you glad to see more of Kit Harington?
