important in a well-functioning economy", as embodied by Horton's repeated maxim, "I meant what I said, and I said what I meant". Adaptations The book was adapted into a ten-minute animated short film by Leon Schlesinger Productions and released in 1942 as part of Warner Bros. Merrie Melodies series. The short was directed by Bob Clampett and marked the first time a Dr. Seuss work was adapted for the screen and also the only time a WB animated short was licensed to be based on pre-existing work still under copyright. In 1966, Soyuzmultfilm released an 18-minute Russian film adaptation called I Am Waiting for a Nestling. It was directed by Nikolai Serebryakov and won the Silver Medal for Best Children's Film at Tours in 1967. In 1992, Random House released "Horton Hatches the Egg" in its series of Dr. Seuss videos, narrated by Billy Crystal and directed by Mark Reeder. "If I Ran the Circus" is second in the double feature video. The book itself was read in a 1994 episode of Kino's Storytime as told by Gordon Jump. Horton appeared again in Horton Hears a Who, published in 1954. The plot of the 2000 Broadway musical Seussical, a retelling of a number of Dr. Seuss books, borrows heavily from both Horton books. Although never adapted into a feature film, the 2008 film adaptation of Horton Hears a Who! references the book, with Horton quoting his most famous line, "I meant what I said, and I said what I meant. An elephant's faithful one hundred percent". While making the 2008 film, Blue Sky Studios and 20th Century Fox briefly got the film rights to Horton Hatches the Egg as a proposed sequel to their adaptation.
