Update: Article at Standard.co.uk - Liv talked about her new TV Series Gunpowder:
The American actress starts work today on the three-part mini-series, which focuses on the events leading up to the failed plot to kill King James I at Parliament in 1605.
Tyler, 39, was at model Natalia Vodianova's Fabulous Fund Fair in Camden last night. She told the Standard: "I have to go up tomorrow to Yorkshire to start filming. I'm enjoying learning about the period, London in the 1600s, the Catholics and the Protestants.
"Obviously I've heard people talk about Guy Fawkes and I was here this year for Bonfire Night, but I never really knew what it meant.
"There was so much more to the plot than just Guy Fawkes, but that’s the guy that everyone knows about.
"The process of film and TV making here is so nice - there is something very free about it. Everyone is very skilled in their jobs no matter what department they are in, and there is something very brave and liberating about the way everyone works. It's not so contrived."
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.
