Before Roy Scheider was cast as Brody, Robert Duvall passed, while Charlton Heston made it known that he wanted the role. But Spielberg felt that Heston was too much of a screen hero to play the more blue-collar police chief. As for Quint, the director first approached Lee Marvin, who said no, before pursuing Sterling Hayden (Dr. Strangelove). The latter was interested but could not work for long in the U.S. due to tax problems. So the role went to Irish actor/playwright/novelist Robert Shaw. Jeff Bridges and Jon Voight were considered for Hooper before Spielberg was made aware of the relatively unknown Richard Dreyfuss.
