Tinker Bell is enhanced by an impressive voice cast widely acclaimed for performances on stage and screen.  Mae Whitman (Independence Day, One Fine Day) gives Tinker Bell her first true voice, and Emmy® and Golden Globe® Award winner America Ferrera (Ugly Betty) provides the voice of the mischievous Fawn, an animal fairy. Five-time Image Award honoree Raven-Symoné (College Road Trip) fills the illuminating role of Iridessa, a light fairy; Tony® Award winner Kristin Chenoweth (Pushing Daisies) offers the elegant tones of Rosetta, a garden fairy; and two-time SAG Awardee Lucy Liu (Dirty Sexy Money) plays Silvermist, an endearing water fairy. In addition, singer-songwriter Jesse McCartney lends his voice to Terence, keeper of the pixie dust, and Academy Award® winning actress Anjelica Huston (Prizzi’s Honor) reigns over Pixie Hollow as the voice of Queen Clarion.
