UPDATE: Fire at Jack Nicholson's House Appears 'Accidental'

Two firefighters were transported to area hospitals with serious injuries after working to extinguish a fire in the Hollywood Hills above Studio City in a house owned by , but not one he has lived in for nearly two decades.

A man who was at the home when the fire broke out was said not to be Nicholson, and , who was on the scene, told Studio City Patch that he was unaware that the actor was associated with the property.

“We have not yet interviewed the person in the house at the time, but he was uninjured and he was not Jack Nicholson,” Mottram said.

Fire officials said late Sunday that the fire "appears to be an accidental fire, but the investigation continues to try to identify the exact cause," according to LAFD spokesman Brian Humphrey. 

KTLA Channel 5 reported that although the house is listed as being owned by the Academy Award winner, the current residents are William O’Farrell and actor William Tynan, who starred in The Two Jakes with Nicholson.

One firefighter was transported to Cedars-Sinai Hospital in Los Angeles after wooden beams fell on him and hit his head, and another firefighter was taken to Providence Saint Joseph Medical Center in Burbank for smoke inhalation and chest pains. As of Sunday afternoon, the firefighters were not in a life-threatening situation.

“We were able to contain the fire to the house, and there was a lot of brush and vegetation, but none of the brush or the nearby homes were threatened,” Mottram said. 

Mottram said more than 200 firefighters and three police helicopters responded to the call a little after 8 p.m. Friday night in the windy hills just above Valley View Elementary School. Flames were seen shooting out of the house from Universal Studios and part of the east end of Studio City. Smoke from the fire not only permeated Studio City and the Cahuenga Pass, but into Hollywood and Outpost Drive. 

drove up the hill by himself and came to check on the firefighters at about 10:30 p.m. The councilman said he heard the reports and wanted to check out the scene.

Roads were blocked from Mulholland Drive and down to Pacific View Drive, and 14 firetrucks from Studio City, Hollywood and Sherman Oaks came to the scene.

“When there is a fire in the hills, we don’t take any chances, and it was important to have everyone on hand in case it spreads,” Mottram said. “We didn’t use the police helicopter water drops, but we were ready. The roads around here are long and steep, and it’s a secluded house with heavy brush.”

The single-story house was considered “seriously damaged” by officials. Up the driveway were four addresses. Parents of a neighbor arrived to check on their son’s place. They said he was away on tour with a sports team, but would not identify him.

Director Quentin Tarantino owns a house not far from the area, as does young star, talk show hostess Ricki Lake, comedian Dan Aykroyd, football player/actor Alex Karras, actress Susan Clark and who owns the palatial  

The cause of the fire is still under investigation and firefighters are expected to remain at the scene until after midnight.
