Ariel will be the voice of Sofia The First, which is set in a storybook world.

Sofia starts out life as a regular girl, but when her mom (Sara Ramirez) marries the king, she is whisked off to a glamorous, but sometimes confusing, castle world of royalty, pomp and new step-siblings, Amber and James.

The movie will premiere in 2012.
