A fine prison break movie from Crane Wilbur by way of Eagle-Lion Pictures, Canon City is a very good, tense film, based on a true incident, about a group of men who break of of the eponymous state prison, where the movie was also filmed. There is particular emphasis on two escapees, a reluctant one who is basically a decent guy, and a more aggressive one, who isn't. As portrayed by Scott Brady and Jeff Corey these characters come to life and compel our interest, and in Brady's case sympathy.
As photographed by the masterful John Alton, the picture is a pleasure to watch, as Mr. Alton was a master of light and shadow, and is obviously in his element with this dark story. He brightens things up in the end with a snowstorm, which enables the picture to end on a grace note, and even a feeling of optimism, not wholly justified by the events we have just witnessed.
