To Live and Die in L.A. (1985)

Oscar-winning director William Friedkin's best known film of the 80s has got to be To Live and Die with LA (1985). The film stars William Petersen as Richard Chance, a secret service agent out to nab a criminal kingpin (Willem Dafoe) with the help of his partner John (John Pankow). When John is murdered by the kingpin, Chance swears revenge and goes to such extreme lengths to exact his revenge, that the law he once swore an oath to uphold becomes utterly meaningless. During an early scene in the film, all three men are in a locker room together, and Willem Dafoe and John Pankow both show off their nice, round rumps! Later in the film, a sex scene gives us another look at Dafoe's duff, but the money shot comes when William Petersen gets it on with his lady and reveals not only his heinie, but also a shadowy look at his meat & potatoes!
