A huge blaze broke out on a lot at Universal Studios in Los Angeles this morning alerting over 300 firefighters which tried to stop the fire, which already destroyed a building and threatened the studio's film vault. Apparently, the fire started at around 5 a.m. Sunday morning on a sound stage on a back lot.

LA Times has published a list of sets destroyed. They are: a New York City streetscape, which was rebuilt in 1990 after another fire destroyed the previous one; the King Kong exhibit featuring a 30-foot-tall moving model of King Kong; the "Back to the Future" set featuring the town's square; the Universal Studios video vaults (partially); and the soundstage, where apparently the blaze started.

Though the cause for the fire hasn't yet been identified, but several press reports claim it is possible that filming might have been going on at the time and at least one explosion occurred. One fireman was injured, but his condition is currently unknown.

The fire spread so violently because the sets are made almost entirely of wood. A lot of wood.

Located north of downtown Los Angeles, mostly within Los Angeles County, the Universal Studios theme park, offers visitors the chance to see sets from films such as "Psycho" and Steven Spielberg's "War of the Worlds" as well as television shows like "Desperate Housewives" and "CSI: Crime Scene Investigation."
