This is a decent film, for the most part a very watchable telling of a good true story which is worth knowing about. Gary Cooper is solid in the title role (albeit he is apparently nothing like the real-life Mitchell) and the drama moves along at a reasonable pace.

But for 17 minutes towards the end it rises above that and becomes mesmerising. What makes the difference? Two words: Rod Steiger. The cross-examination scene, where he goads and scorns Cooper mercilessly, is one of those very rare moments in cinema when a performance holds the screen and burns itself into your memory. No matter how many times I have seen this film, I always spend the first hour or so relishing this particular scene. And I am never disappointed.

So watch the film for two reasons: it is good in its own right. A well-played, thoughtful and dignified film about a good man who was ahead of his time. But whatever you do, make sure you don't miss the last half-hour!
