Anna Leonowens is a character, a widowed mother of Louis, a school teacher, King Mongkut's love interest and the female protagonist from the 1999 animated film, The King and I. She is voiced by Miranda Richardson along with Christiane Noll doing her singing voice.
Anna Leonowens is an usual woman from the 1860s and the attractive English widow has come to Siam with the promise of meaningful work teaching and enlightening the Royal Children and the promise of an architectural brick house of her own where she may raise her 10-year old son, Louis outside the Royal Palace.
When she discovers that King Mongkut is rather cavalier about the promises he keeps, she must prove to him that everyone deserves the right to make their own choices. In her own clever way, she proves herself an able, key adviser and a true friend to Mongkut. She convinces him not to fight the approaching British emissaries, but instead to throw a grand ball and prove himself to be a civilized, modern King.
Anna discovers him to be more open-minded and kindhearted than his stubborn, royal facade would suggest. She is just the woman to help Mongkut help himself, if she can survive the battle of wills.
Describing Anna's personality, she is beautiful, headstrong, outspoken, independent, kind-hearted, open-minded, wise, motherly. On the other hand of her personality, she was used to be, feisty, spunky, difficult.
But before she leaves, before Tuptim is about to be whipped until her death and before King Mongkut is alive, she used to be angry, short-tempered, serious, upset and also, she gets emotional.
She is slender with fair skin and beautiful mahogany-red hair, green eyes, red lips and pearl-like earrings on her ears. She wears a blue sleeveless dress with a yellowish-white long puffy sleeved shirt underneath with a small white collar and red tie. Underneath her dress, she wears a white petticoat, white pantalettes, and black heeled boots with white spats. She wears a blue bonnet with a dark blue coat over her dress when she travels to Siam. She has her hair in a bun most of the time.
