Director-screenwriter Oliver Stone, currently the Noam Chomsky of Hollywood filmmakers, is still fully engaged, plugging away and firing on all cylinders. He’ll probably remain that way until the day he drops dead. But from ’86 through ’91 Stone was incandescent and untouchable — Salvador (’86), Platoon (’87), Wall Street (’87), Talk Radio (’88), Born on the Fourth of July (’89), The Doors (’91), JFK (’91). You could extend the streak, I suppose, to Natural Born Killers (’94), even though Heaven and Earth (’93) was a problem. Any Given Sunday (’99) was of course a major rebound. Okay, call it a 13-year streak.
