This review is for the Criterion Collection DVD edition of the film.The Spy Who Came in from the Cold, is based on the novel of the same name by John le Carré. It is about a spy in Berlin who goes into 'forced' retirement and works in a library. He becomes a drunkard but it is later revealed his 'retirement' was only cover to become a double agent for the East Germans. He then falsely defects to East Germany so he can do one last mission.I liked the film a lot and enjoyed the dialogue too. The Criterion edition is a two disc set with great bonus material.Disc one contains the film with the theatrical trailer, Disc two contains audio commentary by Oswald Morris of selected scenes, a 2000 BBC special about le Carré, a gallery of set designs, and a 1985 conversation between between director Martin Ritt and film historian Patrick McGilligan.
