Madam Mim

Information
Madam Mim, sometimes also named Mad Madam Mim, is a fictional character in the Disney movie based on The Sword in the Stone by T. H. White. She was voiced by Martha Wentworth. The character appears in the original version of the novel, but not in the revised version featured in The Once and Future King which is more commonly known. In Italy she is known as Maga Magò. In the film, Madam Mim is a powerful witch living in the woods during King Arthur's youth. She is an old rival of Merlin. Mim is presented as boisterous, mischievous, and rather conceited, a sorceress much impressed with her own power who delights in causing trouble. She is also a somewhat morbid character with a distaste for sunshine and all things wholesome. When Arthur is transformed into a bird by Merlin, Mim catches and attempts to torture him when she discovers him in her home, eventually deciding to try and destroy him, being that she sees all good things as bad ("Yes, and in my book, that's bad!"). This results in a "Wizards' Duel" between her and Merlin for the young boy's life in which both parties transform into a series of animals. Mim was animated by two of Disney's legendary Nine Old Men, Milt Kahl (who also designed the character, refining storyboard sketches from Bill Peet), and Frank Thomas. Kahl animated her initial interaction with Arthur, while Thomas oversaw her famous "Wizards' Duel" with Merlin. Madam Mim's total screen time does not exceed 20 minutes in the film. The Disney version of the character was adopted into the Donald Duck universe where she sometimes teams up with Magica De Spell and/or the Beagle Boys. She has also appeared in the Mickey Mouse universe where she teamed up with Black Pete on occasion and even with the Phantom Blot at one point. She was in love with Captain Hook in several stories; in others, with Phantom Blot. In many European Disney comics, she has lost her truly evil streak, and appears both morbid yet still relatively polite.
