HBO today unveiled plans for a three-part miniseries that will premiere on the pay-cable channel in December. “Gunpowder” stars Kit Harington, Peter Mullan, Mark Gatiss and Liv Tyler.

The project will roll out on three consecutive nights, Dec. 18-20. It’s produced by Kudos, part of Endemol Shine Group, in association with Thriker Films, originally for BBC One.

“Harington, who is also a co-executive producer on the show, has a personal connection to the real-life source of ‘Gunpowder.’ The actor is a descendant of Robert Catesby, the central figure in the story, and plays him in the show,” HBO notes in its announcement.
