1990 film by Peter Hyams
Narrow Margin is a 1990 American neo-noir action thriller film written and directed by Peter Hyams. It stars Gene Hackman and Anne Archer, with James B. Sikking, Nigel Bennett, Harris Yulin and J. T. Walsh in supporting roles. It was released in the United States by TriStar Pictures on September 21, 1990.
Based on the 1952 film The Narrow Margin, it is the first of two RKO reimaginings by Hyams, the other being 2009's Beyond a Reasonable Doubt. The film keeps the same general story, and follows Los Angeles deputy district attorney Robert Caulfield who attempts to keep murder witness Carol Hunnicut safe from hitmen while traveling on a train. However, it changes the moral alignment of some characters, and the setting from the Super Chief route to the Canadian Rockies.
