Gunpowder, which stars Game of Thrones' Kit Harington alongside Liv Tyler and Mark Gatiss, airs on BBC One on October 21. The eagerly-awaited series was filmed in several locations across Yorkshire in early 2017:-
The three-part thriller is based on the Gunpowder Plot, when a group of persecuted Catholics plotted to blow up Parliament in 1605. Instead of the cult figure of Guy Fawkes, the drama focuses on the scheme's driving force - Robert Catesby, a Warwickshire landowner played by Harington. Gatiss plays King James's spymaster Robert Cecil and Tyler is Catesby's cousin Anne Vaux.
