Don Siegel
The montage department at Warner Bros. gave producer-director Don Siegel the necessary tools to impart his signature economical, action-driven style that made films like "Riot on Cell Block 11" (1954), "Invasion of the Body Snatcher" (1955), "The Killers" (1964), "Dirty Harry" (1971) and "Charley Varrick" (1973) such high water marks in the crime and thriller genres. Though Siegel disavowed any notable style, his films were earmarked by their brisk pace, uncompromising violence, and heroes that frequently followed the same moral path as their villains. Siegel's strongest pictures were in collaboration with "Harry" star Clint Eastwood, whose own prominence was boosted by his work with the director in "Coogan's Bluff" (1968) and "Escape from Alcatraz" (1979), among others. There was no denying that Siegel's four-decade career generated some of the most enjoyable and mature crime dramas to come from Hollywood.
