According to Digitalspy.com Liv will be in BBC's three-part series Gunpowder:
Guy Fawkes and Co's failed Gunpowder Plot is one of Britain's best-known tales – and building on that fabled history is BBC One's new upcoming thriller.
The explosive (ha!) three-part series Gunpowder boasts an impressive cast list with Game of Thrones' Kit Harington, Doctor Who's Mark Gatiss and Lord of the Rings' Liv Tyler already signed up to star.
It's set in 1605 and will see Harington putting his dream of going onto Sesame Street on hold to play Robert Catesby, the guy who put together the treasonous plan.
Gunpowder follows Catesby as he struggles as a catholic man in a protestant England, which was dragging him to the edge of financial, social and psychological ruin.
Mark Gatiss plays Chief Robert Cecil, spymaster and head of torture to the catholics. Tyler meanwhile plays Catesby's cousin Anne Vaux, who is the one person worried about the whole idea.
