This was his second Academy Award and the first he earned for his work as a director. "Platoon," which Stone also wrote, depicted the horrors of the Vietnam War through the eyes of a young soldier, played by Charlie Sheen. The movie also starred Forest Whitaker, Kevin Dillon, John C. McGinley and Johnny Depp.

"Thank you for this 'Cinderella ending,'" Stone said after accepting his Oscar for "Platoon." "But I think that through this award you're really acknowledging the Vietnam veteran. And I think what you're saying is that for the first time, you really understand what happened over there. And I think what you're saying is that it should never, ever in our lifetimes happen again. And if it does, then those American boys died over there for nothing, because America learned nothing from the Vietnam War."
"My special thanks go to my cast and crew," Stone added. "To Tom and Charlie and Willem. To Bob Richardson, Claire Simpson, Bruno Rubeo, the rest of you. My producers: Arnold Kopelson, Derek Gibson, Alex Ho. To Captain Dale Dye, who gave his heart and soul for the movie. To Marion Billings, Andrea Jaffe, Paula Wagner, Mike Mitchell and Bob Marshall. And to Mr. John Daly, who gave me a shot when nobody else would. And to my wife Elizabeth, whose deep abiding love got me through the despair. Thank you."
Stone was married to second wife Elizabeth Stone for about 12 years. They had two sons and divorced in 1993. Stone married his current wife, Sun-jung Jung, in 1996. They are parents to a daughter, Tara.
Stone won his first Academy Award in 1979. It was given for Best Writing for his screenplay for the 1978 film "Midnight Express" and marked his first Oscar nomination. He won his third and latest Academy Award in 1990, given for directing the movie "Born on the Fourth of July." That film was also nominated for Best Picture.
Stone has been nominated for six Oscars for screenwriting and three for directing. His most recent nomination came in 1996, when he received a screenwriting nod for the movie "Nixon."
