The Narrow Margin Remains Charles McGraw’s Best Lead Role and an Underappreciated Noir at 70

You’ve heard of Humphrey Bogart, and you’ve heard of Robert Mitchum, but Charles McGraw? Maybe not.
With a tough face, sturdy stature and voice of pure gravel, he was a natural fit for the hard-bitten world of film noir. Other than his incongruous matinee-idol cleft chin, there wasn’t the whisper of Hollywood about him; he played a host of cops and criminals, and was eminently convincing whichever side of the law he fell. After spending the 1940s in supporting roles, McGraw had an all-too-brief spell as a leading man at the dawn of the following decade. While it’s not exactly a tragedy that his first two films as lead, Armored Car Robbery and Roadblock, have been somewhat forgotten to history, they’re both engaging movies, elevated immeasurably by his gruffly charismatic presence. His third starring role, however, was where things really got interesting.
In The Narrow Margin, he was again a lawman: Detective Sergeant Walter Brown. Along with his partner, Brown is assigned the task of accompanying Mrs. Neall (Marie Windsor), the recently widowed wife of a mob boss, on a long train journey—at the other end of which she will testify against her husband’s former partners. Of course, there are plenty of interested parties who hope she never reaches her destination, and they kill Brown’s partner before they even get on the train. From then on, only Brown stands between his charge and a bullet.
The Narrow Margin runs 71 minutes, and there’s not a morsel of fat on its lean, strong bones. The main players are all on the train within the first quarter of an hour, and just leave it for a single stop at a station to send a pivotal message. This is a train movie that derives most of its dramatic potency from its central mode of transport: Tiny bunks, cramped corridors, the knowledge there’s no escape until the next destination. The good guys and the bad guys are in such tight proximity, they have to duck and dive and twist around each other as they navigate the train, hiding and seeking. Director Richard Fleischer uses that confined geography in a plethora of visceral, innovative sequences; a blistering bathroom fight scene, so tight and kinetic it makes us feel like a third brawler, marks one of the earliest cinematic uses of handheld cameras.
