HBO has released an intense trailer for their upcoming three-part miniseries called Gunpowder, which tells the story of British activist Guy Fawkes. The series follows Fawkes and his team of provincial English Catholics as they plan to blow up the House of Lords and kill King James I in the early 17th century.

This miniseries looks really good and it has a solid cast that includes Kit Harington, Peter Mullan, Mark Gatiss, Derek Riddell and Liv Tyler.

Even though Guy Fawkes has become the main name associated with the Gunpowder plot, thanks to V for Vendetta, he actually played a minor role in it. The main guy who led the charge was Robert Catesby, and that is who Harington is playing. For some additional information on the series’ treason plot Wikipedia says:

The Gunpowder Plot of 1605, in earlier centuries often called the Gunpowder Treason Plot or the Jesuit Treason, was a failed assassination attempt against King James I of England and VI of Scotland by a group of provincial English Catholics led by Robert Catesby. Although anti-Catholic legislation was introduced soon after the plot’s discovery, many important and loyal Catholics retained high office during King James I’s reign. The thwarting of the Gunpowder Plot was commemorated for many years afterwards by special sermons and other public events such as the ringing of church bells, which have evolved into the Bonfire Night of today.

Gunpowder already premiered on the BBC One in the U.K. and now it’s headed to HBO on December 18th, 2017 at 10pm.
