Guns of Navarone is an incredible movie. It is not the action, the special effects, or the plot that make it so; what puts it above 99% of other movies of the similar genre is the simply amazing acting. Everyone is just amazing in their own way. Peck is perfect as the officer who takes charge of the mission once the CO is incapacitated, Quinn is humorous and intriguing as the Greek corporal who is set on revenge against the enemy and Peck, Niven is extremely entertaining as the extremely facetious, cynical explosives expert, and the rest give the performances of their lives, particularly Darren and Irene Papas. You would be hard pressed to watch this movie and not identify with the vast array of personalities you witness. I've never seen Anthony Quinn better. 10/10.
