Sam Riley has been cast alongside Michelle Williams in Suite Francaise.
The On The Road actor will star in The Weinstein Company's World War II drama, says Deadline.
He will also appear with Kristin Scott Thomas, who is signed up as one of the film's lead roles.
Suite Francaise is based on Irene Nemirovsky's book about a French woman (played by Michelle) who falls in love with a German officer (Matthias Schoenaerts) during the war.
Sam has been brought in to play French soldier Benoit, while Kristin takes the part of Michelle's character's mother.
The film is due to start shooting in the summer for a 2014 release date.
Sam will also appear next year alongside Angelina Jolie in Maleficent, the tale of Sleeping Beauty as told by her evil nemesis.
