This fast-paced Disney endeavor stars
Kim Richards and Ike Eisenmann as two adolescents with acute psychic powers. The kids are actually space aliens, but suffer from amnesia and are unaware of their origins. Pursued by greedy business-mogul
Ray Milland, who wants to harness their special powers for his benefit, Kim and Ike are rescued by likeable camper
Eddie Albert. He and the kids escape to the mountain of the title when Albert's RV suddenly acquires the power of flight. In 1978, the film spawned the sequel
Return from Witch Mountain. ~ Hal Erickson, All Movie Guide
