1.Cinderella herself, Ilene Woods, revealed in this interview that Walt Disney was probably the first person to use double tracked vocals, where the singer records herself singing both the melody and the harmonies. The vocals were then mixed together, creating a seamless effect.
2. The transformation of Cinderella from her torn dress to her ball gown was said to be one of Walt Disney’s favorite piece of animation.
3.Cinderella actually loses a shoe 3 times in the film: first, when she delivers the breakfast trays (causing Lucifer to look under the wrong cup), second, when she is running from the ball, and third, walking down the steps with her new husband.
4. Ilene Woods beat exactly 309 girls for the part of Cinderella, after some demo recordings of her singing a few of the film’s songs were presented to Walt Disney.
