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
