Fires destroy part of legendary Hollywood film production ranch where HBO's 'Westworld' was shot Thousands of people have fled their homes in southern California.

 -- A portion of the legendary Hollywood ranch known as "Western Town," where hundreds of films and television shows -- including HBO's "Westworld" -- has been destroyed.

"We are sorry to share the news that the #WoolseyFire has burned Western Town at #ParamountRanch in Aguora," according to a tweet from the Santa Monica Mountains National Recreation Area. "We do not have any details or photos, but it is our understanding that the structures have burned."

At least two television shows have been affected by the California wildfires that have been raging across at least 50,000 acres of land.

Late Friday, President Donald Trump declared a state of emergency for California, freeing up federal resources to supplement local response efforts to combat three major wildfires blazing across the state.

Trump's declaration allows the Department of Homeland Security and the Federal Emergency Management Agency (FEMA) to coordinate disaster relief efforts to help alleviate the hardship and suffering caused by the emergency on the local population, provide support for emergency measures and free up federal resources.

Earlier on Friday, an HBO spokesperson confirmed that production of "Westworld" has been suspended due to the fires, and writers of the CBS series "S.W.A.T." confirmed that production of their show had been halted as well.

“Due to nearby wildfires, 'Westworld' stopped production earlier today and will resume filming as soon as it’s safe to do so," read a statement from HBO.

Added the "S.W.A.T." writers in a tweet: "Production of @swatcbs has been suspended for the day due to wildfires and unsafe air near our stages. Safety of cast and crew come first. Prayers to all affected by these fires."

About 148,000 residents in Ventura and Los Angeles counties have evacuated or in process of evacuating, including a mandatory evacuation for all of Malibu, according to the Ventura County Fire Department.

Among the celebrity homes reportedly damaged -- if not destroyed -- was the home of Caitlyn Jenner, who posted an Instagram video reporting that she was in a safe house, but wasn't sure what has become of her home.
