The Narrow Margin ★★★★★

If you’re a film noir lover and want to convert others, The Narrow Margin may just be the best movie to give them. It contains several noir components, but is also a fine thriller in its own right. LAPD Detective Walter Brown (Charles McGraw) and his partner are assigned to travel to Chicago to escort a mob boss’s widow (Marie Windsor) to appear before a Los Angeles grand jury. Only some people in the criminal underworld aren’t very excited about that prospect. Early in the film (so this isn’t really a spoiler), Brown’s partner is killed, leaving Brown as the widow’s only means of protection. But once he gets her safely on the train, the trouble’s just beginning…

The Narrow Margin is not only a fine noir thriller, but one of the best train films of all time. Marie Windsor, a frequent noir actress, is always worth watching and is wickedly good in this one. Highly recommended.
