Pete's Dragon (1977)

Synopsis
Based on a story by Hollywood old-timers Seton I. Miller and S. S. Field, Pete's Dragon divides its time between its flesh-and-blood characters and an animated blue dragon. Pete (Sean Marshall), a lonely orphan boy in turn-of-the-century Maine, runs away from his abusive foster family. He stumbles upon a lovable dragon named Elliot, and the two become inseparable companions. Elliot is visible only to Pete, leading the townsfolk to assume that the boy is a trifle tetched. Pete finally finds happiness with his "new" family, lighthouse-keeper Lampie (Mickey Rooney) and his daughter Nora (Helen Reddy, who sings and sings). British comic actor Jim Dale co-stars as the wacky dentist Dr. Terminus. ~ Hal Erickson, All Movie Guide
