Leading film editor has worked on most of Clint Eastwood's directorial efforts and other Eastwood projects since "The Enforcer" (1976). Cox began his career as a production assistant on Francis Coppola's "The Rain People" (1969). He moved to editing with "Farewell, My Lovely" (1975), and has since been one of Eastwood's core crew members, even working on former lover Sondra Locke's directorial debut "Rat Boy" (1986). As Eastwood's style has changed with his subject matter from film to film, so has Cox's editing, adapting with precision to the demands of the different genres--from the percussive, quick-paced actioners "The Enforcer" and "The Rookie" (1990) to the cool ease of the dark Charlie Parker biopic, "Bird" (1988) to the laconic Western classicism of "Unforgiven" (1992). The latter earned Cox his first Oscar.
