In a selfless act of buddy love, motor-mouthed WEDDING CRASHERS star Vince Vaughn brings four rising comedy stars on a tour of 30 U.S. cities in 30 days, all captured in this documentary/stand-up comedy film. The comics that brave this breakneck-pace journey are Ahmed Ahmed, Bret Ernst, Sebastian Maniscalo, and John Caparulo. Patterned after the old Buffalo Bill's Wild West Show, Vaughn's calvalcade of merriment is raunchy and fraternity party-ready, but also surprisingly sweet-natured. Interspersed with Vaughn's skits and the stand-up footage is lots of juicy hand-held tour documentary material: the cities visited, the rowdy fans (including the Katrina victims invited for free), the families of the comics, and plenty of male bonding. Guest stars include John Favreau and Justin Long (in a hilarious pre-tour bit reading Vaughn's part from SWINGERS), and country star Dwight Yoakam (singing a duet with Vaughn). Former child-star-turned-producer Peter Billingsley (A CHRISTMAS STORY) is also aboard, doing skits with Vaughn. Director Ari Sandel keeps the action flowing in a flurry of sound bytes and montage. Best of all is the chance to watch these jokers wrestle with all the anxiety and self-doubt that comes with the territory, then actually change and--in some cases--improve as comedians over the course of the tour. Vaughn holds it together with enough aplomb to surely make old Buffalo Bill proud.
