The fire consumed about two city blocks on the Universal property as a thick cloud of smoke rose thousands of feet into the California sky. Roughly 400 firefighters worked for more than 12 hours to contain the fire. In the process, Los Angeles County officials have said that several firefighters were injured when a pressurized cylinder exploded, in addition to other reports of injuries in the fire.

The fire broke out around 4:30 a.m. on along the road of the New York brownstone facades in the park's back lot. The fire was contained later that morning but still continued to burn into that afternoon.

NBC Universal spokeswoman Cindy Gardner stated that the blaze consumed the King Kong attraction, as well as numerous sets and backdrops for several popular TV shows, such as "House", "Monk", and "Crossing Jordan," as well as films such as "Bruce Almighty" and damaged the famous Courthouse Square set seen in "Back to the Future." The film vault that was damaged contained every film that Universal has ever produced, however the company has "duplicates of everything," as stated by Ron Meyer, president of NBC Universal.

Preliminary damage reports estimate financial costs to run into the multi-million dollar range. The source and cause of the fire is still under investigation. Despite the fire, the MTV Movie Awards show held in the nearby Gibson Amphitheater continued on as planned. 

"It looked like a disaster film," noted a Los Angeles city official when describing the situation.

Update 2: According to city officials, an investigation has determined that a blowtorch used by work men was the source of the fire that razed portions of the park's backlot.

Workers were constructing a roof for the facade of a movie set and finished around 3 a.m. Following procedure, they remained onsite for another hour and then left. A security guard noticed smoke and reported the fire at 4:43 a.m.

Difficulties with water pressure caused delay for firefighters working to put out the flames. To overcome this, they were forced to draw from lakes and ponds at the Studios.

Universal officials have said that there are plans to rebuild the New York streetscape, which itself previously had to be rebuilt after a fire destroyed the preceding screetscape in 1990. The park remained open on Monday.
