GOOD MORNING: What magic can be brewing? George Lucas is off on vacation today — and joining him is Steven Spielberg. You can be sure this will be no vacation from ideas. They had first teamed on “Raiders of the Lost Ark” (1981) then the two sequels, “Indiana Jones and the Temple of Doom” (1984) and “Indiana Jones and the Last Crusade” (1989). They’ve asked me not to divulge the location of the vacation. Today is, of course, the day “Star Wars: Episode 1 — The Phantom Menace” bows around the country. But Lucas will not appear with the film again — until the London opening. He says the next prequel will be completed in three years — “and costs will drop dramatically as the technology (which he’s helped develop) is expanding so rapidly as more people adapt it.” He says “a cast of thousands worked behind the cameras” on the current pic over the 4-1/2 years in production. Aside from the special effects, Lucas credits his actors’ swordplay as being totally real — “It was not speeded up (on camera) and the crew applauded them after the takes.” Before leaving town, Lucas got a report on the last “preview” — an invited (by Peter Chernin) audience of the Fox Entertainment Group, News Corp., and L.A. Dodgers for a screening of “Star Wars” both at the Loews Cineplex Century City and on the lot in the Zanuck Theater with a party following on Stage 8. The movie audiences also included industryites involved with the many Murdoch merrymakers. There was applause at the opening, and cheers following both the spectacular and comedic scenes. Lucas would have loved it. He would have also appreciated the conversations from the guests at the party that followed. Among the 20th toppers, Chernin, Bill Mechanic, Chase Carey and Tom Sherak. Also: David Geffen, Jerry Bruckheimer, Bruce Willis, Lin Shaye, Gillian Anderson, David Arquette, Kenny “BabyFace” Edmonds, Matt Groening, Luc Robitaille, Luke Perry, Courtney Thorne-Smith, David Fincher, Helena Bonham Carter, filmmakers Arnold and Anne Kopelson, Al Sargent (his “Anywhere But Here” next stars Natalie Portman) and Laura Ziskin, plus agency toppers, and below the liners who made up the crowd of 1,000. While guests dined in the eerily lighted, emptied (except for food stations) soundstage, John Williams’ dramatic score backgrounded, and aerialists from the Cirque du Soleil performed overhead. Lucas would have loved this, too. And he would have loved the feeling in the crowd — that “Star Wars” belonged to everybody in the biz. And judging by the crowd that waited for this morning’s 12:01 start at the Chinese theater, “The Phantom Menace” will belong to another generation as well.LOOK FOR MORE REVELATIONS about the O.J. Simpson civil trial when CNN’s “Burden of Proof” cohost Greta Van Susteren moderates a panel of Goldman family attorney Daniel Petrocelli, Fred Goldman, KNBC News’ legal reporter Manny Medrano and juror No. 5, Deena Mullen. The event will follow the May 24 screening of HBO’s docu, “Juror Number 5: 58 days of Duty on the O.J. Simpson Civil Trial” at the DGA. As an attorney, Van Susteren has represented clients in criminal and civil cases but she tells me, “I’ve tried so many cases but I’ve never been a juror. This will be intriguing for me. I’ve been interested (in the Simpson case) since June 12, 1994 when I heard about it while aboard the QEII!” She says she wants to ask Petrocelli why the civil case was so different from the criminal. I want to find out from the juror when it was she decided the case. This will not be another ‘O.J. Simpson show,’ ” she promises. The film debuts on HBO June 1, near the fifth anni (June 12) of the Nicole Simpson-Ron Goldman murders.

Electronic Arts. Sugar Ray Leonard hosted the bash boasting ringmasters Jake La Motta, Ray “Boom Boom” Mancini, Ken Norton — and Red Buttons who was (briefly) a fighter before finding out burlesque was more fun.
