UNIVERSAL CITY, Calif. (AP) – King Kong’s roar was silenced, and Marty McFly won’t be going back to the future anytime soon.

A huge fire raged through a lot at Universal Studios on Sunday and destroyed some of Hollywood’s most familiar backdrops, including the courthouse square from “Back to the Future” and a streetscape featured in “Bruce Almighty,” “Spiderman 2” and “Transformers.”

It was the second fire at the historic site in nearly two decades, leveling facades, hollowing out buildings and creating the kind of catastrophe filmmakers relish re-creating. This time around, thousands of videos chronicling Universal’s movie and TV shows were destroyed in the blaze.

But Universal officials said that they were thankful no one was seriously injured at the theme park and that the damaged footage can be replaced.

“We have duplicates of everything,” said NBC Universal President and Chief Operating Officer Ron Meyer. “Nothing is lost forever.”

Universal officials didn’t immediately say what their plans would be for the site.

The blaze broke out on a sound stage featuring New York brownstone facades around 4:30 a.m. at the 400-acre property, Los Angeles County Fire Chief Michael Freeman said. The fire was contained to the lot, but about 400 firefighters were still trying to put it out several hours later.

The cause of the fire is under investigation. Damage was expected to be in the millions of dollars.

Along with the courthouse square, the famous clock tower used to help send Michael J. Fox’s character through time was damaged, fire officials said. Two mock New York and New England streets used for moviemaking and as tourist displays were a total loss, Los Angeles County Fire Inspector Darryl Jacobs said.

An exhibit housing a mechanically animated King Kong that bellows at visitors on a tram also was destroyed.

All three sites were either damaged or destroyed during another fire at Universal Studios in November 1990. That fire caused $25 million in damage and was started by a security guard who was sentenced to four years in prison after pleading guilty to arson.

Hundreds of visitors who waited for hours outside the park gates were turned away after officials decided not to open the area Sunday afternoon. On a typical weekend day, about 25,000 people visit Universal Studios. NBC Universal said it would reopen the theme park Monday morning.

Mike Herrick of San Diego watched the fire on television from his hotel before deciding to return to Universal Studios for a second day with his wife.

“By gosh, we’re going to go and get whatever we can out of it,” Herrick said. On Saturday, Herrick rode the tram that winds around the studio lot, snapping photos of the King Kong attraction, among other sights.

The fire broke out along New York Street, where firefighting helicopters swept in for drops and cranes dumped water on the flames. A thick column of smoke rose thousands of feet into the air and could be seen for miles.

“It looked like a disaster film,” said Los Angeles City Councilman Tom LaBonge.

At one point the blaze was two city blocks wide, and low water pressure forced firefighters to get reserves from lakes and ponds on the property. Several firefighters suffered minor injuries.

“The water pressure situation was a challenge,” Freeman said. “This fire moved extremely fast.”

Meyer estimated there were 40,000 to 50,000 videos and reels in a video vault that burned but said duplicates were stored in a different location. Firefighters managed to recover hundreds of titles.

The videos included every film that Universal has produced and footage from television series including “Miami Vice” and “I Love Lucy.”

Universal Studios, nine miles north of downtown Los Angeles, has thrill rides and a back lot where movies and television shows are filmed, including scenes from “War of the Worlds,” “When Harry Met Sally” and “Scrubs.”

The fire will not affect the 2008 MTV Movie Awards, which is to broadcast live Sunday night from the Gibson Amphitheatre in the adjacent Universal CityWalk, according to the music network.
