In 1971, audiences were delivered the message that the freewheelin’ sixties were over, and so were the innocent fifties for that matter, when long-legged Clint Eastwood stepped onto the screen as “cop on the edge” Harry Callahan in the groundbreaking crime thriller, Dirty Harry. Other tough-as-nails cops and private eyes followed in Harry’s cynical footsteps, including Shaft, Serpico, and a guy named Popeye Doyle. This new generation of cop film was a marked departure from past crime films, where guys like G-Man Jimmy Stewart would walk proudly through spotless backlots dispatching ne’r-do-wells with precision shots from six-shooters balanced on their wrist. They were a return to the hardboiled, world-weary detectives of the 1940s. Callahan and his compatriots were angry, disillusioned, and cynical.
