A good concert film might have been culled from Vaughn’s 30-date LA-to-Chicago tour in September 2005, which showcased stand-up comedians Ahmed Ahmed, John Caparulo, Bret Ernst, and Sebastian Maniscalco and included bits with Vaughn, Jon Favreau, Dwight Yoakam, Justin Long, and Keir O’Donnell. But this is more like a DVD extra for that film, with family visits, interviews, a few sound bites from the show, and the news that Hurricane Katrina occasioned a few cancellations and benefits en route. Ari Sandel directed. R, 115 min. (JR)
