Arnold Schwarzenegger’s comeback movie is a pretty standard action thriller, which updates Rio Bravo and Assault on Precinct 13 to the present day. Arnie plays a US sheriff in the small, quiet town of Somerton on the Mexican border. The leader of a major criminal gang has just escaped the clutches of the FBI (led by a slumming Forest Whitaker) and is headed straight for Somerton in order to escape justice forever. Only Arnie and his ill-equipped buddies stand in the way. Director Jee-woon Kim (whose The Good, the Bad, the Weird also harked back to the westerns of yore) fails to add much visual interest to this routine adventure, while the lazy casting of Luis Guzmán and Johnny Knoxville as comedy sidekicks pretty much says it all. Even so, after a slow start it does become an enjoyable, if somewhat silly, adventure. Arnold’s acting is creakier than ever, but if you’re in the right mood it’s good for some nostalgic kicks.
