Though Spielberg complied with a request from Zanuck and Brown to cast known actors, he wanted to avoid hiring any big stars. He felt that "somewhat anonymous" performers would help the audience "believe this was happening to people like you and me", whereas "stars bring a lot of memories along with them, and those memories can sometimes ... corrupt the story." The director added that in his plans "the superstar was gonna be the shark". The first actors cast were Lorraine Gary, the wife of then-president of Universal Sidney Sheinberg, as Ellen Brody, and Murray Hamilton as the mayor of Amity Island. Stuntwoman-turned-actress Susan Backlinie was cast as Chrissie (the first victim) as she knew how to swim and was willing to perform nude. Most minor roles were played by residents of Martha's Vineyard, where the film was shot. One example was Deputy Hendricks, played by future television producer Jeffrey Kramer. Lee Fierro plays Mrs. Kintner, the mother of the shark's second victim Alex Kintner (played by Jeffrey Voorhees).
