Based on the novel by William Boyd (who also wrote the teleplay) and directed by Edward Hall ("Strike Back"), "Restless" stars Hayley Atwell ("Captain America"), Rufus Sewell, Michelle Dockery ("Downton Abbey"), Michael Gambon and Charlotte Rampling. The two-part series will air over two weeks, on December 7th and 14th.
Dockery plays Ruth, who discovers in 1976 that her mother (Rampling) has been leading a double life -- Atwell stars as Rampling's younger counterpart, getting involved with an alluring Englishman (Sewell) who trains her in espionage.
Produced by Endor Productions, who did the acclaimed "State of Play" (the basis for the 2009 American film adaptation starring Russell Crowe), "Restless" promises to be a classy endeavor -- and hey, it'll offer a chance to see Lady Mary Crawley in '70s fashions.
"Restless" is a BBC co-production -- Sundance also has New Zealand co-production "Top of the Lake," from Jane Campion," primed to air in early 2013. The network's first wholly original series, "Rectify," will also premiere next year.
