An army of A-list celebs and politicos are expected to show up at the N.C. Music Factory on Sept. 5 for a Hollywood-themed gala hosted by L.A. Mayor – and Dem convention chairman – Antonio Villaraigosa.

The Dish has learned that the Factory’s Fountain Plaza and Osso Restaurant will get a one-night make-over. Picture palm trees, classic L.A. architecture and lots of California wine.

Villaraigosa offered his vision for the party during a recent CLT stopover. Dining at Osso with Factory prez Noah Lazes, His Honor said he’d invite stars.

“I’ll call Eva,” he name-dropped – a reference to former “Desperate Housewife” Eva Longoria, now a national co-chair of President Barack Obama’s re-election campaign.

The event is a benefit gala under the glamorous auspices of The Creative Coalition, an advocacy group for the entertainment community.

Set to perform “Love Shack” and other dance-able hits: The B-52s.

The Dude, Mo Rocca impact players

Looks like the Dude is comin’, man.

We’re talking about movie actor Jeff Bridges, who played The Dude in “The Big Lebowski.” And Rooster Cogburn in “True Grit.” And the whiskey-soaked country crooner in “Crazy Heart” – the part that won him an Oscar.

Bridges is on the tentative attendee list for the Impact Film Festival, set for convention week at uptown’s Mez & EpiCentre Theaters.

He narrated “Hunger Hits Home,” a film about childhood hunger to be shown and discussed.

Also expected to come to the fest: Mo Rocca.

We know him as the snarky-funny guy on “CBS Sunday Morning” and NPR’s “Wait, Wait – Don’t Tell Me.” But in CLT, he’ll screen “Electoral Dysfunction,” his road-trip pic on how voting works (and doesn’t) in these United (not really) States.

Kennedy clan decamping to CLT

No word on whether Ethel Kennedy will attend “Ethel,” an upcoming HBO doc about her that’s also in the Impact Film Fest lineup. But RFK’s widow – now 84 – will be in CLT.

She’ll join about two dozen members of the Kennedy clan at the DNC, says the Bah-ston Globe.

Grandson Joseph Kennedy III, a candidate for Congress, will introduce a video salute to the late Sen. Ted Kennedy on the convention’s opening night.
