10Return to Oz (1985)
One could easily show Return to Oz to their children by accident, thinking that they would be introducing them to a magical land of innocent fun. The classic 1939 The Wizard of Oz with Judy Garland certainly has its scary parts, but it's got nothing on Return to Oz. The film begins
with our hero Dorothy (Fairuza Balk), who has been feeling a bit sad since her return from Oz. Dorothy’s parents send her to a psychiatric hospital with a nasty-tempered nurse (Jean Marsh), who wants to perform electroshock therapy on her. Fortunately for Dorothy, a thunderstorm hits the hospital and the power goes out. She's able to escape by the nearby river, where she almost drowns. When she wakes up, however, she finds herself back in the magical land of Oz, which has gone to ruin since her last time there.
Return to Oz has been praised for being a rather faithful adaptation of L. Frank Baum’s later Wizard of Oz books. Unfortunately, for any small child watching the film, Return to Oz also has a wicked witch (also Jean Marsh) who exchanges her heads like pieces of jewelry. If your child doesn’t have a sleepless night thinking about the hallway of heads in Return to Oz, then surely the wheelers (human-like creatures that have wheels instead of hands and feet) will do the trick. But at least Return to Oz has a happy ending.
