"Vince Vaughn's Wild West Comedy Show: 30 Days & 30 Nights — Hollywood to the Heartland" is only sporadically wild, but it does indeed go through some Western states. It also ends up feeling about as long and draggy as the title itself.

Vaughn had a clever idea, though, in amassing a group of little-known comics and taking them on a tour across the country, hitting cities like Lubbock, Texas, and Little Rock, Ark., between Los Angeles and his hometown of Chicago.

We get to know the divergent personalities of Ahmed Ahmed, John Caparulo, Bret Ernst and Sebastian Maniscalco both onstage and on the tour bus. We hear their stories of struggling to make it in the grueling business of stand-up and we meet their families, which allows for a bit more emotional investment than you would achieve from a straight-up comedy concert film.

Ahmed, who was born in Egypt but moved with his family to California when he was an infant, draws biting humor from his experiences living as an Arab in the United States post-9/11. The acerbic Caparulo, with his rapid-fire delivery, finds inspiration in his working-class Ohio upbringing.

And Vaughn himself shows his humble, vulnerable side, something we rarely see from the star of "Swingers" and "Wedding Crashers."

But while the comedians are likable, their routines tend to be hit and miss, and director Ari Sandel probably didn't need to show us every single stop along the way. "Wild West" would have worked nicely if it had been an hour long and on late-night cable.

The four comics, all of whom Vaughn plucked from L.A.'s Comedy Store, have been close friends for years and consistently get along well. So there's no tension, nothing dramatic that sucks you in. Not that it needed reality TV-style contrived confrontations, but these guys are all buddies and all is well. And that's a little boring. The worst thing that happens is that the bus reeks by the end of the tour after all those miles, with all that manhood crammed into a small space, making the fellas a little cranky.

But who could blame them for that? Besides, they'll be able to work it into their material someday.
