Sylvester Stallone's filmography is extensive but he is best-known for action films such as "Rambo: First Blood" and for underdog stories such as "Rocky" and its sequels; a full list of his films can be found on the Internet Movie Database (IMDB). He has also been a writer and executive provider on many acclaimed Hollywood projects.
Stallone's first movie was the 1970 "The Party at Kitty and Stud's." He has gone on to star in many films since then in and out of the mainstream, though he is very well-known for his participation in both action films and the culture and memetic content surrounding action films.
Stallone has also starred in the successful action franchise "The Expendables" and has been involved in writing and directing for all films as of 2015. These films trade on common tropes of the action genre and star a bevy of action stars popular throughout the 1980s and 1990s, including Jason Statham, Dolph Lundgren, Jean Claude van Damme and many others.
Including television appearance, Stallone has been on-camera over 600 times. He was still actively making and starring in films in 2015 and still attracts acclaim for his scripting of "Rocky" and for his iconic performance in that film's title role.
