The direction is antiquated (long, boring conversations between two people in underlit offices, as the camera switches from a close-up of one person to a close-up of the other, and so on), and the script is confusing (though it clears up a bit on the second viewing). However, the film is saved EXCLUSIVELY by its cast, and especially by the star chemistry between Michael Caine and Laurence Olivier; the few scenes they share together are the best in the film. Caine pulls off a terrific Russian accent, too. (**)
