Watch the Trailer for Restless, Starring Downton Abbey’s Michelle Dockery

Downton Abbey star Michelle Dockery will be stepping off the Crawley estate and into the world of international espionage this December in the new mini-series Restless, which is set to screen on the Sundance Channel here in the States in just a couple weeks.

Dockery plays Ruth, a young woman who discovers that her mother Ruth was once a spy for the British Secret Service in World War II and has been living a double life ever since.  The two-part series also stars some other notable British talent, including Charlotte Rampling, Hayley Atwell, Rufus Sewell and Michael Gambon. It’s based on a novel by William Boyd who, incidentally, will be penning the next James Bond novel.

The trailer looks quite interesting – and the material actually seems rich enough to support the level of talent involved.

It’s so exciting to see Lady Mary out of Edwardian dress that this can almost be forgiven for being yet another spy show (what with Showtime’s Homeland, USA’s Covert Affairs and BBC/Cinemax’s Hunted on the TV at home and Skyfall dominating multiplexes, does anyone else feel just a bit spied out?).

Restless premieres on the Sundance Channel on December 7, with its conclusion airing the following week on December 14
