POP/ROCK

Playing in the Park: Eric Clapton, Bob Dylan and other legendary survivors from the 1960s brought rock music back to London’s Hyde Park Saturday after a gap of two decades. An estimated 150,000 fans braved unseasonably cold weather to see the aging rockers, and the organizers are predicting that another 120 million around the world will tune in soon to see the concert on television. (The U.S. broadcast will be shown in Southern California by HBO from 8-10 p.m. on July 14.) The Guardian newspaper said the event was “the middle-aged rock lover’s wildest dream come true--an all-day event with a lineup so stellar that Bob Dylan is only a support act.” Dylan played a rocking set leavened by an acoustic version of the rambling “Tangled Up in Blue,” leaving to polite applause. The Who regrouped for the event to stage what was described as the “live debut” of their “Quadrophenia” album, already turned into a feature film in 1980. Zak Starkey, son of Beatle Ringo Starr, played drums. Guitarist Pete Townshend refrained from the guitar-smashing that used to be his trademark, while singer Roger Daltrey wore an eye patch after getting hit with a microphone stand in a rehearsal accident. They drew a rapturous ovation. Top-of-the-bill Clapton started on acoustic guitar with perhaps his most famous song, “Layla,” and followed with a mixture of crowd favorites and old blues songs. The other star of the event, Canadian Alanis Morissette, 22, was not even born when many of the other performers first became known, but she earned her place on the bill thanks to her success on both sides of the Atlantic. Also on hand was Prince Charles, whose charity that aids young unemployed people collected $1 million from the event.

MOVIES

Polanski Project Dropped?: First John Travolta bolted. Now Roman Polanski reportedly is giving up. Polanski halted production of “The Double” a month after Travolta pulled out in a creative dispute, a Paris newspaper reported Sunday. Le Journal du Dimanche said Polanski, working in a Paris studio, decided to “definitively abandon” the film. Travolta walked off the set June 2 during rehearsals, in a dispute over the script of the film to have co-starred Isabelle Adjani. Liteoffer Ltd. and Mandalay Entertainment are suing Travolta, claiming he “undermined” Polanski by demanding rewrites behind the director’s back. The film companies claim Travolta agreed to a $17-million deal, but Travolta’s lawyers say the actor never had a contract to make the movie. Recent reports from Paris said that Steve Martin had agreed to replace Travolta; there was no immediate explanation of Martin’s status in the project.

Welcome to Warnerland: Warner Bros. opened its own version of a European theme park Saturday in Germany with celebrities including Sophia Loren, Michael Douglas, Claudia Schiffer and Chris O’Donnell providing the glamour. Warner Bros. Movie World, which is something akin to Euro Disney in France, is located outside the Ruhr Valley city of Bottrop. The attractions are pegged to Warner cartoons and movies. Visitors take a make-believe ocean voyage with Bugs Bunny and Daffy Duck from Hollywood to Germany on the Looney Tunes ride. During the Batman ride, visitors help Batman track down the Penguin in a hair-raising chase above, through and below Gotham City. The park also has an Old West town, a middle-America-style Main Street, a 3-D cartoon theater--and five movie studios of its own. The park officially opened Sunday.

TELEVISION

Happy Birthday: When Court TV was launched five years ago today, nobody but founder Steven Brill imagined that Americans would sit in their living rooms watching endless court trials. But now--does the name O.J. ring a bell?--Court TV has become an established media outlet. The legal channel--available on just a few cable systems in Southern California--notes its anniversary at 7 tonight with a live, 90-minute panel discussion on the justice system. Panelists include attorney Johnnie Cochran. But, while celebrating its birthday, Court TV is more interested in looking ahead, not back. Later this year, the network--which reaches 26 million cable subscribers nationwide--finally will become profitable. In the fall, look for Court TV to start a test run of regional versions of the national channel. Court TV executives say that Georgia, New York, Florida and Texas are probable sites for the regional channels.

RADIO

‘No Posturing’ Here: When public radio station KPCC-FM (89.3) starts its new format today, an all-news/talk format will air from mornings until 8 p.m., when a mix of album/alternative roots music replaces the previous eclectic musical mix. A key morning feature will be “Talk of the City” (9-11 a.m.) with Larry Marino, a former out-of-town commercial radio host, and occasional fill-in for Program Director Larry Mantle. “Talk of the City,” with guests and call-ins, is “not going to be posturing, bashing, negativism or banal,” Marino notes. “We’re going to look at the issues in depth.” Station officials plug the show as a compatible segue to Ray Suarez’ live NPR program, “Talk of the Nation,” whose new time slot (11 a.m.-1 p.m.) will allow West Coast listeners to call in. The changes are prompted by new Corp. for Public Broadcasting guidelines, which will require KPCC to boost both its ratings and listener support to maintain federal financial support.
