CANNES, France - After creating a worldwide buzz on opening night with Tom Hanks and “The Da Vinci Code” crew, the Cannes Film Festival heads into its first weekend with a hefty showing of big-screen stars.

The Rock and Sarah Michelle Gellar are here with “Southland Tales” and the entire “X-Men: The Final Stand” cast will make an appearance. Ditto for the folks who voiced characters in “Over the Hedge.”

Beyonce and Jamie Foxx are coming to preview 20 minutes of “Dreamgirls” and uberdirector Oliver Stone will screen 20 minutes of “World Trade Center” before a 20th anniversary screening of “Platoon.”

Ethan Hawke and Greg Kinnear will be on hand for “Fast Food Nation,” a movie inspired by the bestseller. And Penelope Cruz, who has already won praise for her turn in Pedro Almodovar’s “Volver,” will be here amid the buzz that she’s in the running for the festival’s Best Actress prize awarded on May 28.

Yesterday, Elijah Wood, low-key and sporting a buzz cut, was here in the south of France as one of the many stars in the omnibus film “Paris, Je T’aime,” which features 18 five-minute shorts by filmmakers Alexander Payne, Wes Craven, Gus Van Sant, the Coen Brothers and Gurinder Chadha.

“It was intriguing by the nature of directors from all over the world to tell a story from their perspective about love in Paris,” said Wood. “Interestingly enough, I agreed to be in the project before I found out that my short would be about a vampire love story. It was icing on the cake.”

Other “Paris” people on the red carpet at the Palais Du Festival screening: Maggie Gyllenhaal and Peter Sarsgaard, Gena Rowlands, Juliet Binoche and Nick Nolte.

Judd bugs out

Ashley Judd didn’t come to Cannes for her tour de force in “Bug,” one of the most disturbing horror movies imaginable.

Based on the hit off-Broadway play and directed by the legendary William Friedkin (“The Exorcist”), “Bug” boasts Judd’s first nude scene as it charts the mental disintegration of her Oklahoma divorcee as she sinks into a mutually insane paranoid relationship with a man (Michael Shannon) who is convinced he has bugs devouring his system.

By the way, it’s hardly a glamorous scene since she’s soaked in blood and gasoline, by the way.
