LOS ANGELES — A fast-moving wildfire in Southern California has scorched a historic movie site recently used by the HBO series "Westworld." It also prompted numerous celebrities to join thousands of others who have fled flames that have claimed homes and forced an evacuation of Malibu. Kim Kardashian West, Scott Baio, Rainn Wilson and Guillermo del Toro are among those who have evacuated their homes. Some, like del Toro and Caitlyn Jenner, did not know the fate of their homes, but the wind-driven wildfire has destroyed the home of "Dr. Strange" director Scott Derrickson. The blaze started Thursday night. By Friday, it had pushed toward Malibu and the Pacific Ocean, prompting evacuations in Malibu, Calabasas, Aguora Hills and other nearby areas. "Westworld" set at Paramount Western Town ranch The Woolsey Fire reached the ranch that has been the set of numerous movies over the years. The 2,700-acre ranch located between Malibu and the Conejo Valley was purchased by Paramount Sudios in 1927. Western Town specifically was built for TV productions in the 1950s and was used for TV series including "The Cisco Kid" and "Dick Powell's Zane Grey Theatre." Filming continued for decades even as the ranch changed hands. It was acquired by the National Park Service in 1980 but has continued to function as a filming location, serving as a location for the first two seasons of the sci-fi series "Westworld." HBO expressed concern for "all those affected by these horrible fires."

It is also the home of the Topanga Banjo•Fiddle Contest & Folk Festival held annually every May. The Bachelor Mansion The Woolsey Fire reached the Bachelor mansion, according to reports, after Mike Fleiss, head of reality programming for ABC and the creator of The Bachelor, tweeted Friday that the mansion was "in grave danger." Entertainment Tonight reported Friday afternoon the Villa De La Bina, as it's called, was partially destroyed by the fire. The latest season started filming at the mansion in September, but has since moved to other locations. The location is home to three structures. The lower house was destroyed, according to The Hollywood Reporter.
