Tony Award winner Ralph Fiennes will star in the new film "Tinker, Tailor, Soldier, Spy," penned by Tony-nominated Frost/Nixon playwright Peter Morgan, according to Variety.
Fiennes, who earned a Tony for Hamlet and an Academy Award nomination for "The English Patient," will be featured alongside Colin Firth, Gary Oldman and Michael Fassbender.
Tomas Alfredson will direct the film that is based on the John Le Carre novel of the same title about clandestine affairs within the British Secret Intelligence Service set against the backdrop of the Cold War.
Morgan received an Academy Award nomination for the screenplays to "Frost/Nixon" and "The Queen," which earned the Golden Globe for Best Screenplay.
"Tinker, Tailor, Soldier, Spy" will begin filming in London this October.
