Having spent much of his directorial career emulating Don Siegel and John Ford, Clint Eastwood borrows a page from the catalogue of Sam Fuller in Heartbreak Ridge. Eastwood casts himself as an old-fashioned Marine Corps sergeant who is out of step with the new-fashioned military. He returns to his old outfit as a gunnery sergeant, where he runs afoul of 1980s-style superior officers to whom the words "Gung Ho" are foolish anachronisms. But through his tough tutelage, Eastwood's lackadaisical platoon is whipped into a first-rate fighting machine, favoring teamwork over such New Age gobbledygook as "self-fulfillment." Eastwood's men prove their mettle during the invasion of Grenada.
