Dorothy Gale in the context of "The Wizard of Oz"

Wicked (known in full as Wicked: The Untold Story of the Witches of Oz) is a musical with music and lyrics by Stephen Schwartz and a book by Winnie Holzman. It is loosely adapted from Gregory Maguire's 1995 novel Wicked: The Life and Times of the Wicked Witch of the West, which itself was based on L. Frank Baum's 1900 novel The Wonderful Wizard of Oz and its 1939 film adaptation. Set in the Land of Oz before and after Dorothy Gale's arrival from Kansas, the musical explores the complex relationship between Elphaba Thropp and Glinda Upland — the future Wicked Witch of the West and Glinda the Good, respectively — as they are tested by their contrasting perspectives, shared love interest, and reactions to the Wizard's corrupt rule, culminating in Elphaba's tragic fall.

Produced by Universal Stage Productions with producers Marc Platt, Jon B. Platt and David Stone, director Joe Mantello and choreographer Wayne Cilento, the original production of Wicked premiered on Broadway at the Gershwin Theatre in October 2003, after completing pre-Broadway tryouts at San Francisco's Curran Theatre in May and June of that year. Its original stars included Idina Menzel as Elphaba, Kristin Chenoweth as Glinda, Norbert Leo Butz as Fiyero, and Joel Grey as the Wizard. Despite mixed reviews, the production won three Tony Awards and seven Drama Desk Awards, while its original cast album received a Grammy Award.

The Oz books form a book series that begins with The Wonderful Wizard of Oz (1900) and relates the fictional history of the Land of Oz. Oz was created by author L. Frank Baum, who went on to write fourteen full-length Oz books. Baum styled himself as "the Royal Historian of Oz" in order to emphasize the concept that Oz is an actual place on Earth, full of magic. In his Oz books, Baum created the illusion that characters such as Dorothy and Princess Ozma relayed their adventures in Oz to Baum themselves, by means of a wireless telegraph.

After Baum's death in 1919, publisher Reilly & Lee continued to produce annual Oz books, passing on the role of Royal Historian. Ruth Plumly Thompson took up the task in 1921, and wrote nineteen Oz books. After Thompson, Reilly & Lee published seven more books in the series: three by John R. Neill, two by Jack Snow, one by Rachel Cosgrove Payes, and a final book by Eloise Jarvis McGraw and Lauren Lynn McGraw. The forty books in Reilly & Lee's Oz series are called "the Famous Forty" by fans, and are considered the canonical Oz texts.

Judy Garland (born Frances Ethel Gumm; June 10, 1922 – June 22, 1969) was an American actress and singer whose career spanned four decades. She is known for her artistic range and strong contralto voice, working in a variety of genres including musicals, comedies and dramas. Her career and personal life, marked by both public fascination and private struggle, made her a cultural icon and gay icon.

Garland began her career at the age of two: performing with her two older sisters as a vaudeville act called the Gumm Sisters. In 1935, aged 13, she signed a contract with Metro-Goldwyn-Mayer (MGM) and was initially cast in supporting roles in ensemble musicals such as Broadway Melody of 1938 (1937) and Thoroughbreds Don't Cry (1937). She achieved international recognition for her portrayal of Dorothy Gale in the musical film The Wizard of Oz (1939). She followed this with leading roles in MGM musicals including Meet Me in St. Louis (1944), Easter Parade (1948), and Summer Stock (1950). She expanded her range with dramatic performances in A Star Is Born (1954) and Judgment at Nuremberg (1961), both of which earned her Academy Award nominations.

The Wonderful Wizard of Oz is a 1900 children's novel written by author L. Frank Baum and illustrated by W. W. Denslow. It is the first novel in the Oz series of books. A Kansas farm girl named Dorothy ends up in the magical Land of Oz after she and her pet dog Toto are swept away from their home by a cyclone. Upon her arrival in the magical world of Oz, she learns she cannot return home until she has destroyed the Wicked Witch of the West.

The book was first published in the United States in September 1900 by the George M. Hill Company. It had sold three million copies by the time it entered the public domain in 1956. It was often reprinted under the title The Wizard of Oz, which is the title of the successful 1902 Broadway musical adaptation as well as the 1939 live-action film.

The Wicked Witch of the West is a character in the classic children's novel The Wonderful Wizard of Oz (1900) by the American author L. Frank Baum, who is the evil ruler of the Winkie Country, the western region in the Land of Oz. She is inadvertently killed by the child Dorothy Gale with a bucket of water. In Baum's subsequent Oz novels, the Wicked Witch of the West is referred to occasionally.

Margaret Hamilton played the role of the witch in the classic 1939 film based on Baum's novel. Hamilton's characterization introduced green skin, a feature repeated in later literary and dramatic representations, including Gregory Maguire's 1995 revisionist novel Wicked (as well as the novel's 2003 stage musical adaptation and subsequent two-part film adaptation), the 2013 film Oz the Great and Powerful, and the television series Once Upon a Time.

"Over the Rainbow", also known as "Somewhere Over the Rainbow", is a ballad by Harold Arlen with lyrics by Yip Harburg. It was written for the 1939 film The Wizard of Oz, in which it was sung by actress Judy Garland in her starring role as Dorothy Gale.

About five minutes into the film, Dorothy sings the song after failing to get Aunt Em, Uncle Henry, and the farmhands to listen to her story of an unpleasant incident involving her dog, Toto, and the town spinster, Miss Gulch (Margaret Hamilton). Aunt Em tells her to "find [her]self a place where [she] won't get into any trouble". This prompts her to walk off by herself, musing to Toto, "Someplace where there isn't any trouble. Do you suppose there is such a place, Toto? There must be. It's not a place you can get to by a boat, or a train. It's far, far away. Behind the moon, beyond the rain", at which point she begins singing.
