With loud buzz about its premiere screening coming out of the Venice Film Festival and a U.S. release date recently shifted to December, 'Tinker Tailor Soldier Spy' is well on its way toward becoming an Oscar favorite later this year. The adaptation of John Le Carré's famed espionage novel features a cavalcade of British stars that would make even Harry Potter blush, including Gary Oldman in the lead role of George Smiley. It wouldn't take much of a leap to assume that Focus Features will position Oldman's work as the type of late-career crowning achievement that the Academy loves to recognizes. If so, this featurette about his 'Tinker Tailor' character does well to get that ball rolling. Watch ahead.
