GOOD MORNING: Woody Allen and Mia Farrow are married in TriStar’s “Husbands & Wives,” which is skedded for a Sept. 25 release. And nothing in their personal lives is going to change that date. Or the trailers, which have already gone out for the movie, in which their onscreen relationship also fails. “But it’s a great movie,” TriStar’s Mike Medavoy promises. He also promises that Mia will not be in Woody’s next movie for ‘em, which he’s started to write. … The sudden emergence last week of chess champ Bobby Fischer in Yugoslavia– after a 20-year disappearance–isn’t going to affect Par’s “Searching for Bobby Fischer,” now shooting in Toronto, sez producer Scott Rudin. “I’m not concerned. It can only be good, to help publicize the picture,” says Rudin of the Steve Zaillian story (he also directs). “He (Fischer) is never seen in the movie–he never appears.” But one of the real-life characters in the Fischer story does appear — and she’s played by Shelley Winters. Rudin claims he can use Fischer’s name because “he’s a public figure.” … Added to the public figures from Hollywood in Houston today for the GOParty are Bruce Willis and Randy Travis. … Meanwhile, Roseanne and Tom Arnold helped bow the Hollywood Clinton-Gore offices while Christine Lahti and Callie Khouri ditto’d in SanFran. … Voiceover king Joe Sirola will be TV/radio voice for the Clinton campaign. … And TV politix are back in front of the cameras again as NBC’s “The Powers That Be” is shooting for a midseason replacement spot. … In case you wondered about that autographed picture of Johnny Carson hanging on the set of Garry Shandling’s “The Larry Sanders Show”–Carson gave the foto to Larry, I mean to Garry, when the latter was researching his HBO series, which had a boffo HBO bow last Saturday. Fred de Cordova showed Shandling the backstaging of the “Tonight” show as well. And de Cordova does not accept the fact that Rip Torn’s role is drawn from Fred. “I don’t think it’s true to life,” laughs de Cordova, “I’m taller than Torn.”WE ARE FLYING by the seat of our pants. We’re within a hair’s breadth of luck every day,” admitted director Martha Coolidge from the Ludlow, Ky., location of “Lost in Yonkers.”"Every half-hour to half-hour the weather changes. We can’t finish a scene. We change scenes five to six times a day. In a hanging-out-laundry scene (it’s 1942), because of weather changes, it took us four days to shoot!” But it doesn’t faze Neil Simon, who is on the set regularly. “He loves to rewrite,” says Coolidge. “And he comes up with new jokes all the time.” Simon has moved his play 50% outside in the adaptation for the screen. One of those “outside” scenes is a Cincy cemetery with tombstones dating pre-Civil War. The Col movie, produced by Ray Stark, stars Richard Dreyfuss and Mercedes Ruehl, Irene Worth and intros Brad Stoll and Mike Damus. And the movie’s being brought in “for a price.” That’s somewhat over $ 15 million. … Jimmy Caan joins Dennis Quaid and Meg Ryan in “Flesh & Bone,” directed by Steve Klovis for Mark Rosenberg and Paula Weinstein. … With the offbeat baseball pic “A League of Their Own” hitting a home run, Dawn Steel’s warming up “Mr. Kaufman” by Avery Corman and Diana Sokolow. It too is screwball, or rather knuckle ball. “Kaufman’s” a 45-year-old high school principal whom the majors discover has a great knuckle ball And then of course, there’s the upcoming Tom Selleck-starrer, “Mr.Baseball,” with the ex-major leaguer making his comeback via Japan. … And with the success of the western genre represented (and how!) by Clint Eastwood’s “Unforgiven,” Fess Parker tells me he now plans to put his “After Sundown” in production. “I’d like to make one more picture,” says Parker. And this would be it. He first acquired the true story set in Douglas, Ariz., back in 1966 and has written the screenplay himself. “The whites aren’t better than the Indians in this story,” says Fess. “And there are no six-guns shooting, but” he says it’s a warm story worth telling. IT’S BEEN A CLIFFHANGER, but “Cliffhanger’s” in the home stretch and due to wind this week in Italy. Sylvester Stallone tossed an early wraparty for 200 cast/crew members last Saturday at the Cavalieri Hilton, having private birthday-partied g.f. Jennifer Flavin on Friday. … Dino Conte and Disney toppers birthday-partied “Born Yesterday’s” director Luis Mandoki on his 37th. This movie’s also about to wrap following its D.C. locations. … Barbra Streisand, vacationing in the Hamptons at Donna Karan’s home, is also house-hunting back there. … The Princess Grace Foundation-USA’s second-anni gala will be held Nov. 12, Grace’s birthday, at Lincoln Center’s N.Y. State Theater. Prince Rainier, Prince Albert and Princess Caroline will be honored guests at a “Celebration of Young American Artists,” presented by the N.Y. City Opera and the Foundation.

At the party, Corinna Fields reminded Haley she met husband Freddie at one of Haley’s parties. There was plenty of meeting and mixing of singles at this one as well.
