This athletically built, dark-haired U.S. actor/screenwriter/director of European parentage may never be mentioned by old-school film critics in the same breath as, say, Richard Burton or Alec Guinness; however, movie fans worldwide have been flocking to see Stallone's films for over 30 years, making "Sly" one of Hollywood's biggest-ever box office draws.

Born on July 6, 1946, in New York's gritty Hells Kitchen, the young Stallone attended the American College of Switzerland and the University of Miami, eventually obtaining a B.A. degree. Initially, he struggled in small parts in films such as the soft-core "The Party at Kitty and Stud's" (1970), the thriller "Klute" (1971) and the comedy "Bananas" (1971). He got a crucial career break alongside fellow young actor Henry Winkler, sharing lead billing in the effectively written teen gang film "The Lord's of Flatbush" (1974). Further film and TV roles followed, most of them in uninspiring productions except for the opportunity to play a megalomaniac, bloodthirsty race driver named "Machine Gun Joe Viterbo" in the Roger Corman-produced "Death Race 2000" (1975). However, Stallone was also keen to be recognized as a screenwriter, not just an actor, and, inspired by the 1975 Muhammad Ali-Chuck Wepner fight in Cleveland, Stallone wrote a film script about a nobody fighter given the "million to one opportunity" to challenge for the heavyweight title. "Rocky" (1976) became the stuff of cinematic legends, scoring ten Academy Award nominations, winning the Best Picture Award of 1976 and triggering one of the most financially successful movie franchises in history! Whilst full credit is wholly deserved by Stallone, he was duly supported by tremendous acting from fellow cast members Talia Shire, Burgess Meredith and Burt Young, and director John G. Avildsen gave the film an emotive, earthy appeal from start to finish. Stallone had truly arrived on his terms, and offers poured in from various studios eager to secure Hollywood's hottest new star.

Stallone followed "Rocky" (1976) with "F.I.S.T" (1978), loosely based on the life of Teamsters boss "Jimmy Hoffa", and "Paradise Alley" (1978) before pulling on the boxing gloves again to resurrect Rocky Balboa in the sequel "Rocky II" (1979). The second outing for the "Italian Stallion" wasn't as powerful or successful as the first "Rocky"; however, it still produced strong box office. Subsequent films "Nighthawks" (1981) and "Victory" (1981) failed to ignite with audiences, so Stallone was once again lured back to familiar territory with "Rocky III" (1982) and a fearsome opponent in "Clubber Lang" played by muscular ex-bodyguard Mr. T. The third "Rocky" installment far outperformed the first sequel in box office takings, but Stallone retired his prizefighter for a couple of years as another mega-franchise was about to commence for the busy actor.

The character of Green Beret "John Rambo" was the creation of Canadian-born writer David Morrell, and his novel was adapted to the screen with Stallone in the lead role in "First Blood" (1982), also starring Richard Crenna and Brian Dennehy. The movie was a surprise hit that polarized audiences because of its commentary about the Vietnam war, which was still relatively fresh in the American public's psyche. Political viewpoints aside, the film was a worldwide smash, and a sequel soon followed with "Rambo: First Blood Part II" (1985), which drew even stronger criticism from several quarters owing to the film's plotline about American MIAs allegedly being held in Vietnam. But they say there is no such thing as bad publicity, and "John Rambo's" second adventure was a major money spinner for Stallone and cemented him as one of the top male stars of the 1980s. Riding a wave of amazing popularity, Stallone called on old sparring partner Rocky Balboa to climb back into the ring to defend U.S. pride against a Soviet thrt in the form of a towering Russian boxer named "Ivan Drago" played by monosyllabic Dolph Lundgren in Rocky IV (1985). The fourth outing was somewhat controversial with "Rocky" fans, as violence levels seemed excessive compared to previous "Rocky" films, especially with the savage beating suffered by Apollo Creed, played by Carl Weathers, at the hands of the unstoppable "Siberian Express".

Stallone continued forward with a slew of macho character-themed films that met with a mixed reception from his fans. Cobra (1986) was a clumsy mess, Over the Top (1987) was equally mediocre, "Rambo III" (1988) saw Rambo take on the Russians in Afghanistan, and cop buddy film "Tango & Cash" (1989) just didn't quite hit the mark, although it did feature a top-notch cast and there was chemistry between Stallone and co-star Kurt Russell.

Philadelphia's favorite mythical boxer moved out of the shadows for his fifth screen outing in "Rocky V" (1990) tackling Tommy "Machine" Gunn played by real-life heavyweight fighter Tommy Morrison, the great-nephew of screen legend John Wayne. Sly quickly followed with the lukewarm comedy "Oscar" (1991), the painfully unfunny "Stop! Or My Mom Will Shoot" (1992), the futuristic action film "Demolition Man" (1993), and the comic book-inspired "Judge Dredd" (1995). Interestingly, Stallone then took a departure from the gung-ho steely characters he had been portraying to stack on a few extra pounds and tackle a more dramatically challenging role in the intriguing "Cop Land" (1997), also starring Robert De Niro and Ray Liotta. It isn't a classic of the genre, but "Cop Land" (1997) certainly surprised many critics with Stallone's understated performance. Stallone then lent his vocal talents to the animated adventure story "Antz" (1998), reprised the role made famous by Michael Caine in a terrible remake of "Get Carter" (2000), climd back into a race car for "Driven" (2001), and guest-starred as the "Toymaker" in the third chapter of the immensely popular "Spy Kids" film series, "Spy Kids 3-D: Game Over" (2003). Showing that age had not wearied his two most popular franchises, Stallone has most recently brought back never-say-die boxer Rocky Balboa to star in, well, what else but "Rocky Balboa" (2006), and "Vietnam veteran Rambo" (2008) will reappear after a 20-year hiatus to once again right wrongs in the jungles of Thailand.

Love him or loathe him, he has built an enviable and highly respected career in Hollywood; plus, he has considerably influenced modern popular culture through several of his iconic film characters.
