This movie is one of my favorites. Lee Remick and Charles Bronson were the perfect pair for this thriller. Donald Pleasance was also well casted. Who cares if a KGB uniform was not exactly correct as some people have commented on! When I see a movie I want to be entertained and this one had me on edge from beginning to end. Bravo! I would love to get a copy of this film as these type of movies are ones that you could watch over and over again. The chemistry of Lee Remick and Charles Bronson happened as soon as they laid eyes on each other and their performances were excellent. I was also intrigued by the surprise ending
