Synopsis by Mark Deming

L. Frank Baum's enduring fantasy story gets a new and very funny spin in this made-for-TV comedy. Dorothy (Ashanti) is a young woman who works in a diner in Kansas owned by her Aunt Em (Queen Latifah) and dreams of one day making it big as a singer. When a tornado makes its way through the trailer park Dorothy and Em call home, the young woman is spirited off to a magical land known as Oz, where she accidentally kills the most wicked witch in the land. Dorothy, however, isn't so sure she wants to stay, and sets off to find a wizard who might be able to help her. As Dorothy searches for the wizard's castle, she makes some friends along the way -- a scarecrow (Kermit the Frog, voiced by Steve Whitmire), a cowardly lion (Fozzie Bear, voiced by Eric Jacobson), a combination robot and computer made of tin (The Great Gonzo, voiced by Dave Goelz) -- but she also has to fend off The Wicked Witch of the West (Miss Piggy, voiced by Eric Jacobson), whose sister fell victim to Dorothy upon her arrival in the strange new land. Featuring most of the best-known Muppet Show characters, The Muppets' Wizard of Oz also features guest appearances by Jeffrey Tambor, David Alan Grier, and Quentin Tarantino.
