Homeland star Damian Lewis has joined the big-screen adaptation of John Le Carre novel Our Kind Of Traitor.
Scottish actor Ewan McGregor and Bond actress Naomie Harris have already been cast in the movie, playing an English couple on holiday in Marrakech.
Lewis will play a member of British intelligence in the film, made by Bleak House, Parade's End and Nanny McPhee Returns director Susanna White.
The spy thriller, which also stars The Girl With The Dragon Tattoo's Stellan Skarsgard and The Tudors actor Jeremy Northam, begins shooting in London on Wednesday.
Swedish actor Skarsgard plays a Russian millionaire who "propels the couple on a tortuous journey through Paris to a safe house in the Swiss Alps, to the murkiest cloisters of the City of London and its unholy alliance with Britain's Intelligence Establishment".
The script has been penned by Hossein Amini.
Lewis, who starred as Nicholas Brody in Homeland, is tipped to play Henry VIII in a new TV adaptation of Hilary Mantel's bestselling novels.
He is also set to star opposite Nicole Kidman in Queen Of The Desert, about the life of archaeologist, writer and explorer Gertrude Bell.
Our Kind Of Traitor was first published in 2010.
