Charlotte's Web is a 1973 American animated musical drama film produced by Hanna-Barbera Productions and Sagittarius Productions and based upon the 1952 children's book Charlotte's Web by E. B. White. The film, like the book, is about a pig named Wilbur who befriends an intelligent spider named Charlotte who saves him from being slaughtered. Released to theaters by Paramount Pictures, Charlotte's Web features a song score of music and lyrics written by the Sherman Brothers, who had previously written music for family films like Mary Poppins (1964), The Jungle Book (1967), and Chitty Chitty Bang Bang (1968). It is the first of only three Hanna-Barbera features not to be based upon one of their famous television cartoons, Heidi's Song (1982) and Once Upon a Forest(1993) being the other two. Charlotte's Web was recorded in 1972 and released on February 22, 1973, to moderate critical and commercial success. The film has developed a devoted following over the following years due to television and VHS; in 1994 it surprised the marketplace by becoming one of the best-selling titles of the year, 21 years after its first premiere. No other non-Disney musical animated film has enjoyed such a comeback in popularity, prompting a direct-to-video sequel, Charlotte's Web 2: Wilbur's Great Adventure, which Paramount released in the US on March 18, 2003 (Universal released it internationally), followed by a live-action film version of the original story, which was released on December 15, 2006.
