What Parents Should Know
Parents need to know that there are a number of different scenes in this movie that may be scary for children. Many adults still remember the flying monkeys or Dorothy looking into the crystal ball and seeing her aunt turn into the witch. Parents should talk to children about the story before seeing the movie, and watch with them to gauge their reactions.

Families can talk about the way that the Scarecrow demonstrates his intelligence, the Tin Woodman demonstrates his heart, and the Lion demonstrates his courage. Even the humbug Wizard finds that he had the means to go home all the time. Dorothy, who in the first part of the movie runs away from home to try to solve her problems, spends the rest of the movie trying to get back. Even if the story is just a dream (in the book, it is a real adventure), this makes a great deal of emotional sense, a way of working through her inner conflicts.There is something especially satisfying about the way that the main characters find what they need within themselves.

It is also worth talking about the scene in which Dorothy and her friends disregard the Wizard's plea to "pay no attention to the man behind the curtain" and discover that he is really just an ordinary man. This can be a touchstone or metaphor for many kinds of challenges children face. It can help them recognize that the overpowering figures in their lives (parents, teachers, adults, sports figures) are just imperfect human beings. And it can also help them recognize attempts, by themselves as well as others, to distract people in hopes of hiding our imperfection and vulnerability.

Common Sense Media Review
Dorothy Gale ( Judy Garland) lives in Kansas with her aunt and uncle and her dog, Toto. Mean Miss Gulch (Margaret Hamilton) swears she will have Toto taken away. Auntie Em and Uncle Henry support Dorothy, but they are too distracted by the coming tornado to pay much attention to her. Dorothy dreams of a place "over the rainbow" where everything is beautiful, "troubles melt like lemon drops" and "the dreams that you dream really do come true." She starts to run away to protect Toto, but is sent back home by the kindly Professor Marvel (Frank Morgan), a traveling fortune-teller.

When the tornado arrives, Dorothy is outside the shelter. She goes to her room, where she is hit on the head by a piece of wood torn loose by the wind. The whole house rises, and is carried away by the tornado.

The house lands with a crash, and when she opens the door, she finds she has landed in the colorful world of Oz (the movie, black and white until this point, becomes technicolor). Her house has landed on the Wicked Witch of the East, killing her, and the tiny Munchkins celebrate Dorothy as a great heroine. Their friend Glinda the good witch (Billie Burke) arrives and gives her the Wicked Witch's magic ruby slippers, just as the Wicked Witch of the West (Margaret Hamilton) arrives to take them. The Wicked Witch of the East was her sister. Furious, she swears revenge. Dorothy wants to go home and is told to seek out the Wizard of Oz, who lives in the Emerald City, for help.
