Return from Witch Mountain

Return from Witch Mountain is the 1978 sequel to Walt Disney Productions' 1975 film, Escape to Witch Mountain. It was written by Malcolm Marmorstein and is based on the novel by Alexander Key. Ike Eisenmann, Kim Richards, and Denver Pyle reprise their roles as Tony, Tia, and Uncle Bené—humanoid extraterrestrials with special powers including telepathy and telekinesis. The two main villains are played by Bette Davis as Letha Wedge, a greedy woman using the last of her money to finance the scientific experiments of Dr. Victor Gannon, played by Christopher Lee.

Having spent a good deal of time enjoying the company of their newfound family and friends at Witch Mountain and intensively studying and practicing their supernatural powers, it is decided that Tony and Tia deserve a vacation in Los Angeles, California. Uncle Bené drops them off in their flying saucer in the Rose Bowl Stadium, after which they quickly become separated from each other. Dr. Gannon and Letha happen to see Tony using his powers to save their henchman from certain death, and realize that Tony has supernatural powers. So Dr. Gannon drugs the boy with a tranquilizer shot and takes him back to their lab. There, he successfully tests the doctor's new mind-control technology on him. Under the hypnotic mind control, Tony does everything that his kidnappers want him to do; from stealing gold to trying to stop Tia from finding him. With Tony at his robotic bidding, Dr. Gannon hopes to achieve recognition within the scientific community and worldwide power, while Letha merely wants a return on her investment.

Tia must find Tony and foil the villains' nefarious plans. Fortunately, a group of would-be toughs, called the Earthquake Gang, and hapless truant officer Mr. Yokomoto — whom the toughs call "Yo-Yo" — come to her aid.
