The Dreamer of Oz: The L. Frank Baum Story

The Wizard of Oz (1933) is a Canadian animated short film directed by Ted Eshbaugh.
 The story is credited to "Col. Frank Baum."
 Frank Joslyn Baum, a Lieutenant Colonel in the United States Army and eldest son of writer L. Frank Baum, was involved in the film's production, and may have had an involvement in the film's script, which is loosely inspired by the elder Baum's novel, "The Wonderful Wizard of Oz".
 It runs approximately eight and a half minutes and is nearly absent of language, working mainly with arrangements of classical music created by Carl W. Stalling.
The Wizard of Oz in Concert: Dreams Come True was a 1995 television musical performance based on the 1939 film "The Wizard of Oz" (starring Judy Garland).
 The book and score of the film were performed on stage at Lincoln Center to benefit the Children's Defense Fund.
 The concert featured guest performers including Jackson Browne as the Scarecrow, Roger Daltrey as the Tin Man, Natalie Cole as Glinda, Joel Grey as the Wizard (a role he reprised in "Wicked"), Jewel as Dorothy, Nathan Lane as the Cowardly Lion, Debra Winger as the Wicked Witch, and Lucie Arnaz as Aunt Em.
 The Boys Choir of Harlem appeared as the Munchkins, and Ry Cooder and David Sanborn performed as musicians.
Timon and Pumbaa are an animated meerkat and warthog duo introduced in Disney's 1994 animated film "The Lion King".
 Timon was portrayed through his many appearances by Nathan Lane (in all three films and early episodes of the show), Max Casella (the original actor in "The Lion King" Broadway musical), Kevin Schon (in certain episodes of the show), Quinton Flynn (in certain episodes of the show), Bruce Lanoil in the "Wild About Safety" shorts and "Kingdom Hearts II", and while Pumbaa is voiced by Ernie Sabella (in all of his animated speaking appearances), and was portrayed by Tom Alan Robbins in the original cast of the Broadway musical.
 In the upcoming live-action remake, the characters will be portrayed by Billy Eichner and Seth Rogen respectively.
 Nathan Lane and Ernie Sabella first came to audition for the roles of the hyenas, but when the producers saw how well they worked together they decided to cast them as Timon and Pumbaa.
 Lyricist Tim Rice however was pulling for Rik Mayall (for Timon) and Adrian Edmondson (for Pumbaa) to play the roles, as he got the idea for the lyrics to "Hakuna Matata" by watching their show "Bottom".
The Cowardly Lion is a character in the fictional Land of Oz created by American author L. Frank Baum.
 He is an African lion, but he speaks and interacts with humans.
The plays of L. Frank Baum are an important aspect of Baum's writing career about which some of the least is known.
 While even most brief biographies, long before the Internet, have noted Baum's work as a playwright, these works have been rarely performed beyond his lifetime, and almost none have been published aside from two scenarios and a first act of three unfinished works in "The Musical Fantasies of L. Frank Baum", compiled with an introduction by Alla T. Ford.
 Aside from his youthful success with "The Maid of Arran", his blockbuster eight-year run with "The Wizard of Oz", his failure with "The Woggle-Bug", and "The Tik-Tok Man of Oz" as source material for his novel, "Tik-Tok of Oz", very little is known about his dramatic output, and mostly from the publications of Michael Patrick Hearn, Susan Ferrara, and Katharine M. Rogers.
 Hearn identifies 41 different titles in the bibliography of the 2000 edition of "The Annotated Wizard of Oz", plus one play without a title, although some of these titles clearly refer to drafts of the same play, such as the early titles of "The Tik-Tok Man of Oz".
Roger Stanton Baum (born 1938) is a former banker and stockbroker, and currently (as of 2005) a children's author, residing in Las Vegas.
 Baum publishes under the name Roger S. Baum.
 Baum is a former resident of Los Angeles.
 He also tours the country, reading from and signing his children's books.
 Baum is a great-grandson of L. Frank Baum, the original creator of the "Oz" series, and grandson of Frank Joslyn Baum, who published "The Laughing Dragon of Oz" in 1935.
 Many of Roger S. Baum's children's books are set in the same world.
The Maid of Arran, An Idyllic Irish Drama Written for the People, Irrespective of Caste or Nationality is an 1882 musical play by L. Frank Baum, writing and performing under the pseudonym, "Louis F. Baum", based on the novel "A Princess of Thule" by William Black.
 It was described as "A Play to Ensnare All Hearts and Leave an Impress of Beauty and Nobility Within the Sordid Mind of Man."
 The play resets the novel from Scotland's Outer Hebrides to Ireland (although Arran is actually in Scotland—Baum probably meant Aran, but never changed it).
 This was a well-received melodrama with elaborate stage effects, including a storm upon a ship, and an original score by Baum himself.
 Unfortunately, only the songbook for the windows use survives, which omits two of the songs referenced in the script (the manuscript did not include the lyrics).
 Baum played the main character, Hugh Holcomb, originally called Frank Lavender in the novel, in its initial tour (including two stints on Broadway), and later played Con.
 O'Mara, the heroine's father, in a community theatre revival.
L. Frank Baum's Juvenile Speaker: Readings and Recitations in Prose and Verse, Humorous and Otherwise is an anthology of literary works by L. Frank Baum, author of the Oz books.
 The book was first published in 1910, with illustrations by veteran Baum artists John R. Neill and Maginel Wright Enright; a subsequent 1912 edition was retitled Baum's Own Book for Children.
 The book constitutes a complex element in the Baum bibliography.
Father Goose: His Book is a collection of nonsense poetry for children, written by L. Frank Baum and illustrated by W. W. Denslow, and first published in 1899.
 Though generally neglected a century later, the book was a groundbreaking sensation in its own era; "once America's best-selling children's book and L. Frank Baum's first success," "Father Goose" laid a foundation for the writing career that soon led to "The Wonderful Wizard of Oz" and all of Baum's later work.
The Dreamer of Oz: The L. Frank Baum Story is a 1990 made-for-television biographical film starring John Ritter as Lyman Frank Baum, the man who wrote "The Wonderful Wizard of Oz" and thirteen of the other Oz books.
 Also starring in this TV movie was Annette O'Toole as Baum's supportive wife, Maud, and Rue McClanahan as Baum's tough mother-in-law, Matilda Gage.
 John's son, Jason Ritter, makes his debut in this telefilm as Harry Neal Baum.
 At the time of the film's debut, O'Toole and Ritter also starred in "It", a TV miniseries where they played a couple.
