For a mid range movie of 1950 this fast moving Railway Police/chase story packs a reasonable wallop. The cast is above average for what looks like a 'double feature' production and the script never wanders from its target for a moment. The police are shown realistically and situations are not compromised in their general graphic details. All characters are written and directed as you might expect them to be in a life challenging situation. Perhaps the somewhat tacked on ending could do with a little (very minor) editing to give it a harder edge but some may be happy with finishing it on a slightly lighter note.
Maybe Lyle Bettger could also have been reined in a tad with his full-on performance of the nasty kidnapper but he looks the part. Sydney Boehm's tight screenplay was based on Thomas Walsh's Edgar winning novel 'Nightmare in Manhattan' - William Holden and Nancy Olson were teamed again for Award winner, 'Sunset Boulevard' the same year and the image and sound on the DVD I viewed, was quite clean. Was good to discover another classic from the past.
