Peter Hyams Narrow Margin is a sleek thriller that attempts to blend courtroom intrigue with a single location white-knuckler, which it does.. mostly successfully. A better way to put it would be that it sandwiches a cat and mouse game set on a speeding train between an intro and epilogue both set in the decidedly more complicated realm of legal escapades. We open as an unfortunate lawyer (J.T. Walsh in a too brief cameo) is assassinated by the mobster scumbag (Harris Yulin, creepy as ever) he had shady ties too. A terrified Anne Archer hides in the shadows, witness to the murder, and therefore a valuable asset to the dogged prosecutor (Gene Hackman) who is trying to bring the kingpin down. The two of them are ambushed on a routine transport via helicopter and escape onto said train, and here’s where the narrative cops out just a little bit. Almost the entire rest of the film is spent on the train, an extended diversion of a set piece that steps in for what I thought would be a more cerebral battle of wills between these factions, in court and out. It’s not a huge deal, I was just expecting a little more, and the bits at either end of the film stand as my favourite sequences. Hackman plays stubborn like no other, having both literal and figurative tunnel vision here, the only one thing he cares about being the life of his witness. They’re harried at every turn by corrupt officials of many kinds, and pursued by a mystery woman (Susan Hogan, my acting mentor in college no less), while the train hurtles through the gorgeous Canadian wilderness, captured pristinely by Hyam’s lens as he dutifully does his own cinematography, the dynamo. It’s a thrilling little piece that benefits from Hackman’s spirited work, the photography and editing backing it up nicely.
