Although Marge Belcher was unquestionably the main model for Snow White, several other girls apparently shot similar scenes for the rotoscope. History does not say whether their work was used in the final rendering, but it contributed to the development of some scenes.

For example, Ward Kimball tells us in an interview with David Johnson that his wife Betty, who was working in the painting and inking department at the time, shot a scene that was supposed to depict Snow White running over a small bridge (presumably scenes 2AX and 2BX, sequence 3C).

In another interview heard in a Walt Disney Family Museum podcast, she even confirms that a sequence was animated in relation to her diction and movements, and Adriana Caselotti told her that she had difficulty delivering the line to match her rhythm, which was different from hers.
