Downton Abbey star Brendan Coyle is to star in a new series for French premium channel Canal+.

Spotless is being described as a “sexy one-hour crime drama peppered with black humour”.

The ten-part first season will be set in London and tells the story of Jean, a troubled man whose life is turned upside down when his outlaw brother Martin reappears on the scene.

So far confirmed in the cast are Coyle, Spooks actress Miranda Raison and Denis Ménochet, who was in Quentin Tarantino’s Inglourious Basterds.

Spotless has been co-created by Ed McCardie (Shameless) and Corinne Marrinan (CSI) with the first two episodes to be directed by French filmmaker Pascal Chaumeil (A Long Way Down).

“We love Pascal Chaumeil's work and are excited that he will be directing the first two episodes, starting the series off in a quirky, off-beat style,” said Fabrice de la Patellière, director of French drama and co-productions for Canal+.

Spotless will begin principal photography in London in July.
