the nursery went through many alterations. In one version, it is Mrs. Darling who finds Peter Pan's shadow and shows it to Mr. Darling, as in the original play. In another version of the film, Nana goes to Never Land with Pan and the Darling children, the story being told through her eyes. In another interpretation of the story, John Darling is left behind for being too serious, practical and boring, but story artist Ralph Wright convinced Disney to have John go with the others to Never Land. This adaptation also included Wendy bringing her Peter Pan picture book and Peter and the children eating an "imaginary dinner". At one point, a party in Peter's hideout was conceived at which Tinker Bell becomes humiliated and, in her rage, tells Captain Hook the location of Peter Pan's hideout of her own free will. However, Disney felt that this story was contrary to Tinker Bell's character; instead, he had Captain Hook kidnapping Tinker Bell and persuading her to tell him. In Barrie's play, Captain Hook puts poison in Peter's dose of medicine and Tinker Bell saves Peter by drinking the poison herself, only to be revived by the applause of the theater audience. After much debate, Disney discarded this story development, fearing it would be difficult to achieve in a film. In earlier scripts, there were more scenes involving the pirates and mermaids that were similar to those with the dwarfs in Snow White and the Seven Dwarfs. Ultimately, these scenes were cut for pacing reasons. The film concept was also a bit darker at one point than that of the finished product; for example, there were scenes involving Captain Hook being killed by the crocodile, the Darling family mourning over their lost children and Pan and the children discovering the pirates' treasure loaded with booby traps. Animation Live-action reference As with previous Disney animated features since Snow White and the Seven Dwarfs (1937), a live-action version with the actors performing to a prerecorded dialogue track was filmed to serve as an aid to animators. Margaret Kerry received a call to audition to serve as the live-action reference for Tinker Bell. For the live-action reference, Kerry said she had to hold out her arms and pretend to fly for all the scenes requiring it. Additionally, Kerry served as reference for one of the mermaids, along with Connie Hilton and June Foray. At
