Downton Abbey’s Michelle Dockery Joins the Cast of Restless

Downton Abbey star Michelle Dockery is set to join Rufus Sewell, Michael Gambon, Charlotte Rampling and Hayley Atwlell in the BBC’s upcoming two-part adaptation of William Boyd’s best-selling novel Restless.

Dockery will play Ruth, a young girl who discovers that her mother Sally is really a spy named Eva, who was recruited by the British Secret Service at the start of World War II and has been living a double life on the run ever since. Rambling and Atwell will both play Eva, thirty years apart. Sewell and Gambon will also pull double character duty, both playing Lucas Romer, Eva’s former handler and lover. It all sounds quite complicated – but very interesting too!

Acclaimed theater director Ed Hall has signed on to run things behind the scenes, and Boyd – whose Any Human Heart  aired on Masterpiece last year – will be adapting his own novel for the small screen.

"To have the chance to film a novel like Restless over three hours is the sort of opportunity that only a television adaptation can provide,” Boyd said.

"It represents the most enticing and alluring of possibilities - not only to tell an enthralling story of wartime espionage, love and betrayal but also to lift the lid on one of the last secrets of the Second World War."

Restless is due to screen on BBC One in late 2012. No hard date has been established for when we might see this drama here in the States, but the Hollywood Reporter says the project will broadcast in the US “later this year” as well.
