ROLE CALL: Zeta-Jones Breaks Up With Costner

Apparently Catherine Zeta-Jones has more important things to do than spend time with Kevin Costner.

The Hollywood Reporter notes that the actress has dropped out of Oliver Stone‘s epic love story “Beyond Borders,” in which she was to co-star with Costner. Sources now have the lead role going to “Pretty WomanJulia Roberts.

The shoot for Mandalay Pictures’ “Beyond Borders” was to begin in May. No word from Zeta-Jones‘ camp on why she dropped out of the flick, although the actress is due to wed Michael Douglas — reportedly on Sept. 25, the lovebirds’ shared birthday.

HE WRITES THE SONGS: Steve Martin may be headed back to the Barry Manilow era in Miramax’s upcoming “Long Lost.”

Martin‘s attached to star and Griffin Dunne (“Addicted to Love“) is set to direct, the Reporter says. “Pulp Fiction‘s” Lawrence Bender and Laura Bickford will produce.

The story’s about a 1970s Manilow-esque pop icon whose days of having women throw their panties at him are long since past.

ANIMAL PLANET: Warner Bros. has a certain pet fetish after taking a gander at the box-office numbers for Sony’s mousecapade, “Stuart Little.” Daily Variety reports that the studio is a kibble and bit away from green lighting its own live action-animated pet movie, “Cats and Dogs.”

Warners initially had hoped to fast track the project for a release Christmas Y2K but may take its time to have the pic set for a 2001 holiday release.

The fast-and-furry comedy tells the story of a continuing battle between the species, as dogs and cats go paw to paw over the creation of a vaccine against dog allergies. The dogs are barking for it. The cats want to scratch it from existence.

Director Larry Gutterman has already begun scouting locations, and creature models are being built in L.A. and the United Kingdom.
