After graduating high school, he went to the American College of Switzerland on an athletic scholarship. As a girls' athletic coach there, Sly had his first acting experience, starring in the lead of Arthur Miller's "Death of a Salesman". Inspired by this, he went back to the States to study drama in Miami, and in the late 1960s moved back to New York City. While working at different jobs, he also was in several Broadway productions. His deep voice and his face would sometimes not get him good roles. He then turned to writing scripts. In 1974, he wrote the successful "The Lords of Flatbush", which helped him get better roles. But his next script about a boxer with big dreams turned Sly into a Hollywood star. "Rocky" was released in 1976 and went to be on of the most successful movies of all time, and also winning the Oscar for Best Picture, Best Director, and Best Actor nomination for Stallone. In 1982, he co-worte the action film, "Rambo: First Blood". Rambo became just as popular as Rocky Balboa, which led to the two sequels, both written by Sly. He co-wrote, directed and produced "Staying Alive" and starred in "Nighthawks", "Victory", "Tango & Cash", "Lock Up" and "Rocky V". Sly has starred in "Get Carter", "Cliffhanger", "Demolition Man", "The Specialist", "Assassins", "Daylight" and "CopLand". Sly was also the winner of the People's Choice Award for Favorite Motion Picture Actor and was recently given the Lifetime Achievement Award by the USA
