Richards portrays the roadside waitress and Eisenmann portrays the Sheriff in a re-imagined remake of the original film Race to Witch Mountain, released in March 2009. Jack Soo (Mr. "Yo-Yo" Yokomoto) was diagnosed with esophageal cancer in the autumn of 1978, several months after the film's release. Return from Witch Mountain would be his final movie appearance, as he died the following January. The emergency voice heard over Yokomoto's minibus radio—announcing the problem at the plutonium plant—is that of Gary Owens. Filming locations Filming started on April 11, 1977. The otherwise vacant lot, upon which the children's dilapidated mansion hideout stands, was at the Alameda Street railroad yard in California, where the Rochester House (a relic from the 1880s) was waiting for restoration and relocation. The house was never restored and was ultimately demolished in 1979. Scenes of Dr. Victor Gannon's mansion, the location of his laboratory, were filmed at Moby Castle on Durand Drive, Hollywood Hills, Los Angeles. The tunnel scenes were filmed at the Fillmore and Western Railway in Fillmore, California constructing a faux tunnel structure. The faux tunnel still stands and can be seen from CA-126/Telegraph Road. The gold bar robbery sequence was filmed at the Natural History Museum in Exposition Park, Los Angeles. The building facing the park's Rose Garden was used for exterior shots of the museum. The scene in which Yokomoto's minibus is overturned and breaks a fire hydrant was filmed near the Sunset Boulevard bridge and Glendale Boulevard underpass intersection, in the Echo Park district.
