There’s some terrific chemistry in The Messenger, but surprisingly, it’s not in the romantic couple the film sets up. As a young soldier wounded in Iraq reassigned to “casualty notification” and his older, more seasoned partner on this unpleasant mission, Foster and Harrelson dig into their roles and feed on each other’s dramatic energy. But the script sends Foster’s character into a romance with a widow (Jena Morton) he’s just informed of her husband’s death. It feels like an unnecessarily melodramatic line of drama. The real thrill here is elsewhere, watching Harrelson and Foster find new twists on the old pro/rookie dynamic. Oscilloscope’s snazzy set includes a feature-length commentary with Moverman and his actors, two featurettes and a recycled slip sleeve.
