There's no humor, hugging, or understanding in this buddy-cop movie, just bare-knuckled brawn and car chases that'll give your ticker a workout. As Detective Jimmy ''Popeye'' Doyle, Gene Hackman (pictured, background) is the original unlovable cop bastard, an amoral racist with a drinking problem. Hackman owns the movie — and he won an Oscar for the role — and his partner Det. Buddy ''Cloudy'' Russo (Roy Scheider, foreground) seems to spend most of the film just trying to get out of his way. But when Popeye accidentally kills a fellow officer, Russo doesn't turn him in. Now that's a true buddy.
