The King and I is a 1999 American animated musical film directed by Richard Rich. It is the only animated feature film produced by Morgan Creek Entertainment. Loosely based on Richard Rodgers and Oscar Hammerstein II's 1951 stage musical of the same name, it portrays a fictionalized account of English school teacher Anna Leonowens' historical encounter with king Mongkut of Siam and the royal court. The voice cast stars Miranda Richardson and Martin Vidnovic as Leonowens and Mongkut, respectively, with Ian Richardson, Darrell Hammond, and Adam Wylie. The score, songs, and some of the character names come from the stage musical. Screenwriters Peter Bakalian, Jacqueline Feather, and David Seidler took creative liberties with the history and with the source material from the musical in an attempt to make the film palatable to all audiences.

Plot

In 1862, a ship sails from London to Bangkok; on board are Anna Leonowens and her son Louis. Kralahome, the Prime Minister, uses his powers of illusion to make it appear as if a massive sea serpent is attacking the ship as it's battered in a storm. Anna, with the help of Captain Orton, manages to save Louis from drowning, and they all manage to fend off the sea serpent by whistling. As they approach Bangkok, the captain explains to Anna how the kingdom is politically structured.
