A convict enlists his wife and his brother to help him bust out. This one has two interesting elements. One, it's actually filmed at San Quentin, lending the picture some realism. Two, both brothers -- although not twins -- are played by Jack Palance. The breakout scheme is beautifully detailed, clever and intricate. It's a nice piece of business. Palance is okay but not at his best, and although Barbara Lang gets the job done, she doesn't leave a lasting impression. Two smaller roles jump out: Harold J. Stone as the creepy guard, and a cellmate played by the great Tim Carey, who can always be counted on for an eccentric performance. I typically enjoy a good prison break movie (much like I enjoy heist films) so I was happy with it, but if you're not a fan of the genre you can probably skip this one. Beyond the mechanics of executing the plan, the film doesn't offer much of interest.
