RESTLESS
Sundance, 9:00 p.m. ET
MINISERIES PREMIERE: Part 1 of 2. Concluding next Friday, this Sundance Channel and BBC-1 co-production teams stars from two of the boldest, most disturbing sexual dramas ever filmed: Charlotte Rampling of The Night Porter and Michael Gambon of The Cook, The Thief, His Wife and Her Lover. Here, their roles are less overt than covert. Rampling plays a former Russian refugee and British spy who fears her real identity is at risk of being discovered decades later; Gambon plays her former handler and lover. In flashbacks, their roles are played, respectively, by Hayley Atwell and Rufus Sewell, and Michelle Dockery, familiar as Lady Mary on Downton Abbey, plays the daughter of Rampling’s paranoid recluse. Quite a cast – and on the heels of Homeland, another TV exercise in seriously shifting loyalties.
