Margaret Kerry

Kerry answered an audition call during the planning stages of the animated feature film Peter Pan. The audition, supervised by Disney animator Marc Davis, required her to pantomime the motions that would eventually be animated as Tinker Bell, such as preening in a mirror at her feet. She won the audition and spent the next six months at the Disney Studios on a mostly empty soundstage pantomiming the role on film. The studios provided props as well, notably a giant keyhole mounted on a stand as well as a pair of giant scissors, later used in the scene in which Tinker Bell became trapped in a jewelry box.

Kerry also served as animation model and voice for the red-haired mermaid in the Neverland lagoon scenes. Disney released the film at about the time Marilyn Monroe had begun to make an impact, and an urban legend immediately sprung up attributing the role to her.
