Fresh from the huge success of their adaptation of War & Peace, work has begun on the BBC's latest literary drama. To Walk Invisible: The Bronte Sisters, written and directed by the award winning Sally Wainwright (Happy Valley, Last Tango In Halifax), has begun shooting, with the streets of York transformed this week for the one off, two hour drama. Finn Atkins, who plays Charlotte Bronte and Charlie Murphy, who has been cast as her younger sister Anne, were both spotted on set on Thursday in their elaborate 19th century costumes.
