GOOD MORNING: Another court appearance is upcoming for Kato Kaelin — this time as a plaintiff. He’s suing Marc Eliot, author of “Kato Kaelin: The Whole Truth” (HarperCollins). Michael Plotkin, Kaelin’s attorney, sez the book agreement was for “a collaboration.” And the publication is in violation of a “property that doesn’t belong to (Eliot).” Last week on “20/20″ Kaelin also told Barbara Walters some statements attributed to him in the book were untrue. And the (court) beat goes on … Former studio owner (and hotel owner and — ?) Marvin Davis admits he, too, has been looking to buy a studio (again). But, he says, “the studios don’t make much money — it’s the music companies they own that are the moneymakers. We looked at a couple. We may yet get with one.” Davis is already invested in musickeries. The Davises will not be on the French Riviera or at Wimbledon this summer. Following his serious surgery, Marvin’s decided to relax next month in the Hamptons, where they’ve rented a house … You must admit Sylvester Stallone is making it easy for photogs — who can recycle pictures of him with former fiancees. No sooner did he and Angie Everhart cancel their engagement last Friday than his former flame Jennifer Flavin appeared on the set of his “Assassins” in Seattle and they jetted off to Hawaii for the Planet Hollywood bow there. Another partner in the Planet eateries, Melanie Griffith, also appeared on the Seattle set, and winged to the Hawaii Planet doings — with her new beau, Antonio Banderas, also co-starring in “Assassins”– and also newly separated.SECRETARY OF THE ARMY TOGO WEST, after viewing a special screening of HBO’s “The Tuskegee Airmen,” noted, “There is a lot of sadness and pride watching this movie. Sadness that the people who contributed so much to their country had to wait so long to be recognized. But, as the picture makes clear … the other airmen who were helped by those fighter squadrons ultimately realized what they owed to the Tuskegee Airmen’s competence, their professionalism and their dedication. You see the same thing in the military today.” Among those on hand for the special screening were Bob Cooper, president of HBO Pictures and Bob Williams, co-exec producer and himself a former Tuskegee airman. The show airs Aug. 19 … Among those who will be attending the 50th class reunion of Fairfax High, Saturday at the Sportsmen’s Lodge, is Larry Gelbart. He didn’t go on to college — but continued working as a writer for “Duffy’s Tavern”– and you know the rest of his successful scripting story sans college diploma. Larry and Gary Markowitz just returned from a drive from Iowa to Wisconsin, doubling the (300 mile) route taken on a sitdown power lawnmower by their “John Deere” feature hero who “drove” the lawnmower to visit his stroke-stricken brother … Fred Hayman was surprise birthday-partied on his 70th by Betty Endo and son Robert Hayman, daughter Nicole and family at the new Beverly Hills Hotel’s Sunset Room. Guests included friends and employees who’ve known Hayman from his hotelier days at the Ambassador and BevHilton to Rodeo Drive. They also included champ George Foremam (whom Hayman suits for all his TV appearances), Gil Cates, whom Hayman advises on wardrobe for the Academy Awards, actors Charlton Heston, Ricardo Montalban, actresses Jackie Bisset, Barbara Rush with designer David Hayes, newscasters Jerry Dunphy, Tawny Little (with Ron Silver), the New Yorker’s Caroline Graham, longtime restaurateur-friends Patrick Terrail, Kurt Niklas, Jimmy Murphy and Victor Drai plus California Pizza Kitchens’ Larry Flax and Rick Rosenfield who are opening a branch in Merv Griffin’s Atlantic City Resorts Casino Hotel on June 28. FOR THOSE WHO WONDERED why producer Tim Burton was the only one missing from the top credits of “Batman Forever” at the giant preem at the Village and Bruin theaters plus party at the Armand Hammer museum — the reason given for his absence — location hunting for his next for WB, “Mars Attacks!” Burton will probably be back to direct “Cat Woman” as well …”I just realized I’ve been combing my hair wrong for 70 years,” sez Leslie Nielsen, who has a new look in “Dracula: Dead and Loving It” for Mel Brooks, natch … A takeoff on “Oliver Twist,” Mira Vista Films’ “Twisted” stars Tony winner Anthony Crivello, Bill Hickey, David Norona, with 26-year-old Seth Michael Donsky directing for producer Adrianne Agramente. Crivello just did workshops on classix “Jane Eyre” and “Camille” and his “Dillinger and Capone” with Martin Sheen and F. Murray Abraham in the title roles comes out on video next week … Ava Fries reports $ 600,000 was raised at the Center Theater Group’s Angels’ Night at the Century Plaza. Ava made a sizable contribution herself — buying five of the art pieces auctioned by Martin Landau, Michele Lee, Dick Van Patten and Robert Stack.
