Based on a novel by Graham Greene, THE HUMAN FACTOR was made as a response to the James Bond films, depicting the business of spying as much more down to Earth and far less glamorous as seen in the Hollywood franchise. With the Cold War as a backdrop, this film reveals the humdrum lives of those in the British spy business, with Nicol Williamson, Richard Attenborough, Derek Jacobi, and Robert Morley making up the numbers as the men fighting to keep their country safe. Mischief arises when it turns out that one of their number is a traitor, and the rest of the film follows up the subsequent investigations. Although it goes on a bit too long and isn't the most exciting film out there, I found much to like about THE HUMAN FACTOR. Otto Preminger's direction is realistic and assured and the ensemble actors are exemplary, as you'd expect, with Williamson in particular shining as the conflicted protagonist.
