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 of the same name 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.
