Paris Hilton, who co-stars in this weekend’s “House of Wax,” makes no apologies for her glaring dirth of cinematic experience.

“Whatever,” Hilton icily explains during a telephone conference call, as if she’s already answered this question six times during the conversation. “That’s how it happened.”

She’s decidedly (and puzzlingly) nonchalant about her first starring role — “(The movie) was a lot of fun,” she says — but the heiress is almost too quick to praise the producers’ “all-star” casting choices.

“We all look good together,” says Hilton, who thinks she was selected “because I’m cute.”

Thankfully this “House” boasts other, more articulate, inhabitants.

Both Elisha Cuthbert and Chad Michael Murray — who recently starred in “The Girl Next Door” and “A Cinderella Story,” respectively — are proud and excited to anchor a film Cuthbert terms “(a throwback to) the scary movies we watched as a kid.”

“It’s a great date movie,” Murray says, laughing.
