GOOD MORNING: When I noted Joel Silver had put his Frank Lloyd Wright landmark Storer house in the Hollywood Hills up for sale at $5.5 million (via Christie’s Great Estates), I wondered why Silver would part with such a great piece of Hollywood history — and something he loved since buying and restoring it in 1984. The answer, from Silver, now vacationing at the Hotel Du Cap: “It’s time to move on — to change my lifestyle, to get married, to have a family.” He and Karyn Fields will wed next summer and he will build a home for the “new life.” Silver will not sell his other Frank Lloyd Wright chef d’oeuvre house in North Carolina. “I will never sell that one,” he says. Silver’s enjoying the biz of “Lethal Weapon 4,” which he says will pass the $110 million mark on Friday and “will be the biggest ‘Lethal Weapon’ we’ve ever had.” He just completed a global p.a. with “4″ in Taipei, Hong Kong (with costar Jet Li, who will next star for Silver in “Romeo Must Die”), and on to Sydney where Silver’s “The Matrix” is shooting. His lifestyle may change, but it doesn’t sound like his work style will … Pat Proft will next parody “Dirty Harry.” Proft says his as-yet-untitled parody is about an American cop who heads to England to extradite a criminal and — well, you can guess how he fouls up. Proft, writer-director of the upcoming “Wrongfully Accused” starring Leslie Nielsen, will also direct this one for Constantine Pictures, backers of “Wrongfully.” The filmmaker, whose past feature takeoff credits include the “Naked Guns,” “Police Academys” and countless TV comedies, today delivers his script of “Deep Titanic: Armageddon” (also known as “Titanic, Too: It Missed the Iceberg”) to Brad Krevoy’s MPCA. Proft wants to direct this one too.TIME MARCHES ON with “American History X,” despite director Tony Kaye’s continuing campaign via ads and a bizarre New Line meeting on its editing in which he was accompanied by a priest, rabbi and Tibetan monk (Daily Variety, July 31). Producer John Morrissey (Larry Turman-John Morrissey Prods.) says New Line, which permitted Kaye to remain in post for a year, has now agreed with Morrissey that the pic is excellent at one hour 55 mins. and, says Morrissey, “We’re cutting negative to be ready for an Oct. 16 release.” A premiere will benefit Amnesty Intl. (the pic’s about the Aryan Brotherhood and one of its ex Neo-Nazi members). Meanwhile Morrissey/Turman just set two vidpic deals: with ABC, “The Negotiator” (natch, gets a new title), about a blind hostage negotiator who, they hope will become a series star a la “Ironsides’ ” wheelchaired Raymond Burr. Their second telefilm is “Tomahawk” for CBS, a dramatic plane-crash survival story. The latter’s a one-shot TV movie. Or is it also a series possibility? The producing team also has the features “What’s the Worst Thing That Can Happen?” at UA and “On Trail of the Dragon” at Propaganda, in preparation … There is a rebirth of Congress and President Franklin Roosevelt’s original intention in creating the USO: Rep. Vito Fossella (R-N.Y.) launches a fundraiser to send performers to entertain the 15,000 men/women stationed in the Persian Gulf in a post-Christmas/New Year’s Eve show in January. The total cost is only $65,000 to get the show to the American troops over there. Of course, top stars are hoped for. And as always the “soldiers in greasepaint” are known for their generosity, donating their talents. Contributions and queries can be directed to the USO, (718) 351-5187. The non-profit USO has been on “active duty” more than 57 years. THE “SAVING PRIVATE RYAN” screening for Academy members at the Samuel Goldwyn Theater brought out an overflow crowd, forcing print-bicycling to an upstairs screening room. Among those viewing Steven Spielberg’s epic was Oscar-winning tunesmith Bob Sherman, who at 17 had enlisted in the Army, was in the 86th Infantry and made his way to within 60 miles of Berlin. He was wounded, received several decorations. His younger brother, Dick Sherman, served in the Korean War … Weather is always a gamble on location and Par’s “The General’s Daughter” is no exception. Production shut down when it found itself in the path of an oncoming tornado and electrical storm. They were shooting on grounds of the Savannah, Ga., Lebanon Plantation, whose owners Mary and Howard Morrison opened the doors of their home to take in the drenched company. The set was under water and temporarily without power … Meanwhile, here in sunny Santa Monica at the Locanda del Lago restaurant, Nicolas Cage and Jim Cameron were lunching. While both men said they want to work together, no specific property was decided upon … Chayanne, who makes his auspicious feature bow with Vanessa L. Williams in “Dance With Me,” signed with ICM. The duo have also filmed a musicvideo of one of the pic’s tunes, “You Are My Home.” And he’ll do a solo video in Miami of a song from the new album he’s recording … The legendary Ray Charles, on tour in the east, plays Radio City Music Hall Thursday, continuing on to Ballys Park Place Casino in Atlantic City, Aug.11-16.
