Dirty Harry
Milius wrote an uncredited draft of "Dirty Harry" (1971). He says his contribution to the film was "A lot of guns. And the attitude of Dirty Harry, being a cop who was ruthless. I think it's fairly obvious if you look at the rest of my work what parts are mine. The cop being the same as the killer except he has a badge. And being lonely." "Dirty Harry" was an enormous box office hit.
