Transsiberian

Woody Harrelson and Emily Mortimer are Americans abroad on a no-frills train ride through the isolated wilderness of the Siberian winter, where they get tangled with drug smugglers (Eduardo Noriega as a charming cad who tempts former wild child Mortimer) and a corrupt Russian narcotics detective (Ben Kingsley). Brad Anderson, who co-wrote as well as directed, makes effective use of the beautiful and unforgiving desolation of the setting. It's a little sloppy and full of convenient coincidences, but at its best roils with edgy character tensions. No supplements on the DVD, but the Blu-ray edition has a "making of" featurette.
