Aspiring Actor
While he waited for his acting career to take off, Stallone worked all sorts of jobs to make ends meet. He cleaned up the lions’ cages at the Central Park Zoo, ushered at a movie theater, and even made an appearance in an adult film called A Party at Kitty and Studs (1970). A few uncredited parts in mainstream films, such as Woody Allen’s Bananas (1971) and Klute (1971), soon followed. He had a more substantial role playing a tough guy in the 1974 independent film The Lords of Flatbush with Henry Winkler and Perry King. Around this time, Stallone married Sasha Czack.
In addition to acting, Stallone had an interest in writing. He created a screenplay about a rough-and-tumble thug who struggles for a chance to make it as a professional boxer. According to several reports, Stallone refused to sell the script unless he was allowed to star in it. Despite having a pregnant wife and little money in the bank, he held out until he found two producers, Irwin Winkler and Robert Chartoff, willing to let him play the lead.
