“If you see something, say something.” That’s what Joyce Willecombe (Nancy Olson) does when she notices a pair of suspicious men in the bustle of Chicago’s Union Station, igniting a suspenseful attempt to foil a kidnapping plot—as well as a potential romance with the cop in charge (William Holden). Union Station packs a double feature’s worth of thrills into its brief running time, including some Dirty Harry–style brutality that was a couple of decades ahead of its time. Ace crime scenarist Sydney Boehm keeps the plot humming like a runaway train and a pair of visual stylists, director (and renowned cinematographer) Rudolph Maté and actual DP Daniel L. Fapp, make the ride more vivid through use of actual locations. Although set in Chicago, Los Angeles’ Union Station served for the interiors. Barry Fitzgerald gives a nasty edge to the elfin Irishman he typically played, and Lyle Bettger is terrifying as leader of the kidnapping gang.
