Oscar nominee Gary Oldman has given multiple interviews discussing the lengths to which he went to find the perfect glasses to wear in portraying George Smiley in “Tinker Tailor Soldier Spy.” And now the same vintage specs that helped him find his character have been donated for a charity auction through the Variety Foundation and its “CharityBuzz” page. The auction is ongoing here, and closes Feb. 27.

In conceiving his role, Oldman conferred with director Tomas Alfredson and costume designer Jacqueline Durran about the  right pair of glasses for Smiley to wear throughout the film. He found the desired pair in the U.S. and brought them to England for filming there. The glasses up for auction are the ones that Smiley acquires and begins wearing in the film, after the prologue and flashbacks, for the duration of the 1970s-era story as he tracks a double agent compromising Britain’s highest espionage ranks. “Tinker Tailor Soldier Spy” is nominated for three Academy Awards.
