Saw this when I was about 14. It turned me into a James Cagney fan. But I've never been able to find the movie. Only saw it the once and have looked for it for years. Thanks for this clip.
The Internet Movie Database shows Alan Hale Jr in this film, right at the start of his film career. His father Alan Sr died in 1950, had only one film listed for 1950, and West Point Story wasn't it.
