What's so scary? Headless queen, Wheelers If you think you're familiar enough with Oz thanks to the classic musical, beware this sequel drenched in hardcore '80s dread. This Disney production was intended for kids, but between the horrifying encounter with the headless queen and the threatened violence of the Wheelers, it ended up sending more kids to the therapist than the library. It should come as no surprise that the director, Walter Murch, had previously worked on such Francis Ford Coppola films as "The Godfather" and "Apocalypse Now." The horror.
