Sylvester Stallone

Sylvester Stallone started his acting career with a soft-core pornography movie. He chose to act in an adult film at a time when he was homeless and sleeping in a bus terminal in New York. He said he saw a casting notice of the porn movie "The Party at the Kitty Stud's (1970)," and contacted the producers. The producers selected him to play the male lead in the movie and paid him $200 as compensation. They didn't release the film for unknown reasons. Five years later, when Sylvester Stallone became very famous with the success of "Rocky", they renamed the movie and released it as "Italian Stallion."  Unsurprisingly, the film helped them to make a lot of money!
