A generic spy story becomes an inspired light comedy with the application of great talent led by the star-power of Walter Matthau. Matthau’s CIA spook hooks up with old flame Glenda Jackson to retaliate against his insufferable CIA boss (Ned Beatty) with a humiliating tell-all book about the agency’s dirty tricks history. Matthau’s sloppy, slouchy master agent is a comic delight; Ronald Neame’s stylishly assured direction makes a deadly spy chase into a wholly pleasant romp. With Sam Waterston and Herbert Lom. On Blu-ray from The Criterion Collection.
