Hollywood goes on alert after FBI warning
By Steve Gorman
LOS ANGELES, Sept 21 (Reuters) - Major Hollywood studios tightened security on Friday -- canceling tours and setting up metal detectors and barriers -- after the FBI warned they could be the "target of a terrorist bombing."
FBI spokesman John McLaughlin said the agency met with the heads of major studios on Thursday hours after receiving an "uncorroborated yet credible" threat against the filmmakers.
The studios warned were Fox Entertainment Group Inc.'s <FOX.N><NCP.AX> 20th Century Fox, Sony Corp.'s <6758.T> Sony Pictures Entertainment, Walt Disney Co. <DIS.N>, Vivendi Universal's <V.N> <EAUG.PA> Universal Pictures, Viacom Inc.'s <VIA.N> Paramount Pictures, Metro-Goldwyn-Mayer Inc. <MGM.N> and AOL Time Warner Inc.'s <AOL.N> Warner Bros.
DreamWorks SKG, the studio co-founded by filmmaker Steven Spielberg, also was believed to have been included.
The studios immediately took several steps to beef up security, shutting entrances to their lots, ordering additional barricades and metal detectors set up and canceling some studio tours.
Warner Bros. suspended all live audiences for the taping of its TV shows during the next two weeks, media reports said.
McLaughlin declined to discuss the source of the threat but said FBI agents met the heads of the studios and their security managers within hours of receiving it.
"The uncorroborated threat states that a film studio in California could be the target of a terrorist bombing attack in retaliation for any bombing attacks by the United States in Afghanistan," he said. "The FBI is working closely with the studios regarding this matter."
PREPARING FOR POSSIBLE ATTACKS
President George W. Bush has been steeling Americans and the nation's allies for looming U.S. military action against those the government believes carried out the attacks on the World Trade Center and the Pentagon. In a televised address Thursday night, Bush demanded that Afghanistan's Taliban rulers hand over Osama bin Laden, who has been living in Afghanistan.
The United States has named him as the prime suspect behind attackers who hijacked four passenger airplanes, smashed two into the World Trade Center and one into the Pentagon. More than 6,500 people are missing or dead. A fourth plane crashed in rural Pennsylvania.
According to trade paper Daily Variety, which said it obtained memos from several studios detailing new security measures, Warner Bros. closed three studio gates on its Burbank lot, set up barricades, and was planning to install armed guard details and metal detectors. All incoming packages were to be X-rayed, and all vehicles would be subject to search.
Universal plans to continue operating its popular -- and profitable -- studio tours, though it is "tightening and increasing security," Variety said.
A memo from Culver City, California-based Sony Pictures said local police would increase their patrols.
"We are taking this very seriously, and as
a result we are implementing all necessary measures to ensure the safety of our employees," said Flo Grace, a spokeswoman for Fox.
A Fox memo warned employees at the Century City-based studio that "we will all be subject to long delays entering the facility," and as a result "we urge you to remain on the lot during the day."
Last week's attacks have forced the studios and television networks to scrap, postpone or tinker with projects that had terrorist-related themes.
Additionally, the TV networks, most of which are corporate siblings of film studios, have lost hundreds of millions of dollars in advertising revenues. The uncertain economic picture has sent media stocks tumbling.
