GOOD MORNING: In case you wondered what Oscar-winner Jack Nicholson’s plans are — he’s playing golf, watching the Lakers and playing with his children — not necessarily in that order. As for working, “I haven’t even read anything” — since winding the campaign on “As Good as It Gets” and, of course, the Academy Awards. “After all,” he reminds, “I peppered the world with five pictures in 2 years.” As for talk that Nicholson would be a volunteer “back-up director” for stroke-stricken and speech-robbed Michaelangelo Antonioni on “Just To Be Together,” Jack says, “I adore Michaelangelo” (they teamed in 1964 on “The Passenger”) — but the project (and deals) never came together. … Fred Roos, who was to produce “Together,” has gone on to ready producing “Town & Country” for New Line starting June 8. Pic stars Warren Beatty, who will probably still be beating the bushes for “Bulworth.” Completing the starring cast of “T&C” are Diane Keaton as Beatty’s wife, Goldie Hawn and her movie husband Gerard Depardieu, and Andie McDowell playing the sex therapist Beatty meets on a plane. Michael Laughlin, who is now scripting, says, “The whole movie is about sex — and therefore it is a comedy!” There’ll also be a lot of music in the movie directed by Peter Chelsom — but there’ll be no rapping by Beatty. The music’s jazz. Also producing with Roos are Andrew Karsch, Sidney Kimmel and Simon Field. Screenwriter Laughlin and producer Roos will team as well on “Him & Her” — also a sexy comedy. This one’s set with the Ohio State U. football team and they’d like to kick it off with — Jack Nicholson as the coach. … On the screen’s baseball diamond, Peter Gent’s father-and-son book, “The Last Magic Summer,” is being scripted by Jim Hart for Nick Nolte to star at Interscope. Hart will also makes his directorial debut in “Summer.”

HOLLYWOOD HELPED CELEBRATE a major auto move — domestic, that is — at the Petersen Automotive Museum Wednesday night. The party marked the headquarters switch of Lincoln-Mercury from Detroit to Southern Calif. It includes sales, brand-marketing, product development, PR and support staffs. Feature and TV producers were on hand well as studio production resources departments to offer welcomes to SoCal — and also to ogle a sample of the millennium: a sleek Lincoln LS (Luxury Sports Sedan), to be intro’d next year, plus the 1999 Mercury Cougar. Ford VP Jim O’Connor hosted. … And Ford expands its product placement internationally with three new offices in Australia. Showcase Placements Inc.’s CEO Dick Taylor, no stranger to Hollywood’s PR world, is currently Down Under setting up film and TV tie-in opportunities there. Next, Europe pix and TV centers. … Add expansion for Trilogy Entertainment, with three new properties at MGM/UA. One is “Labor Pains” and another at Par is “If Not for You”. … Harrison Ford, next seen in “Six Days, Seven Nights” with costar Anne Heche, may have Michele Pfeiffer as his next leading lady — for “Random Hearts.” He plays a Washington detective in the dramatic-love story. … Betty White plays Melanie Griffith’s mom in Griffith’s pilot for CBS. It’s Melanie’s first series — and White’s 11th. In the pilot, Griffith is about to have a baby — by her ex-husband. The show was filmed before a live audience, Griffith’s first such experience, and White, a vet of that kinda showbiz, reports, “I was proud of her.”

TONYS PRODUCER WALTER C. MILLER hopes to do something new for the nominated plays. He’s asked their playwrights to write a (45-sec.) synopsis — to be narrated by one of its leads. “It’s too hard to try and illustrate by a scene,” logics Miller, who wants the plays (which are running) to get something out of the nomination. So far, he says, four of the playwrights have agreed. … The “Scarlet Pimpernel’s” Christine Andreas raced (via police escort) from curtain Thursday p.m. to Russos on the Bay in Queens to perform for the NYPD’s Chiefs’ Honor Legion. And May 31, Christine wings to L.A. for an appearance at “Singing For Life II”. … After the “Chicago” (standing ovation) final curtain at L.A.’s Ahmanson Wednesday, the cast was partied at the Sky Bar and Coco Pazzo at the Mondrian. Among those congratting the cast: Les Moonves, Holly Hunter, Joely Fisher, Robert Forster, Jacqueline Bisset, Adam Arkin, etc. The Barry and Fran Weissler “Chicago” production continues SRO on B’way and London and a second U.S. tour — and Australia bows July 4 in Melbourne. … Happy 75th birthday to Johnny Grant, Mayor of Hollywood. … Shirley Jones bus-parties the cast of her pic, “Gideon,” to the Norris Theater in Palos Verdes, where she concerts tonight. … Sacha Newley, son of Joan Collins and Tony Newley, preems his collection of new paintings at the SPACT Gallery in Venice Saturday. Portraits include Billy Wilder, Oliver Stone, Gore Vidal. … John Asher, son of Joyce Bulifant and Bill Asher, got a greenlight on his second script, “Alien Sky,” from Total Film Group’s Gerald Green following Asher’s first writing-directing efforts on “Chick Flick”
