Benedict Cumberbatch has joined the cast of Tomas Alfredson's upcoming adaptation of John Le Carré's Cold War-set spy novel "Tinker, Tailor, Soldier, Spy" reports The Sunday Times.
The British thesp will play Peter Guillam, the protégé of middle-aged, pen-pushing British intelligence operative George Smiley (Gary Oldman) who must find the identity of a Soviet mole within 'The Circus', the highest echelons of the S.I.S. (MI6).
The half-French Guillam comes from a family with a long history in the S.I.S. and is in charge of the 'Scalphunters', the violent division of 'The Circus'. He essentially serves as Smiley's assistant in the mole hunt, though has personal reasons as he's still carrying the mental scars from his network of informants in French North Africa being compromised and executed.
The actor joins the likes of Colin Firth, Michael Fassbender and Ralph Fiennes who've already been cast in key supporting roles. Peter Morgan ("The Queen," "The Last King of Scotland") adapted the script.
Cumberbatch drew acclaim for his recent performance as Sherlock Holmes in the BBC's contemporary series update of the literary character by producers Steven Moffat and Mark Gatiss. The actor has also appeared in films such as "Atonement," "Creation," "The Other Boleyn Girl," "Four Lions," and "Amazing Grace". He next appears in "The Whistleblower" and the Steven Spielberg-directed "The War Horse".
