Tren Internacional (Valparaiso Express) is the Argentine "answer" to such anglo whodunits as Lad on a Train and Murder on the Orient Express. The film is set on a cross-continent train, where the usual collection of wealthy, suspicious types all congregate. Ingredients essential to the action are a jewelry heist, a romantic triangle, and, of course, a murder. When the train is delayed in the Andes mountains, international thieves Alberto Closas and Mirtha Legrand team up to capture the psycho killer. Supporting actor Joaquin Petrosino was taken to task by contemporary critics for patterning his performance after Sidney Greenstreet, who'd recently passed away. ~ Hal Erickson, Rovi
