Sylvester Stallone’s Biggest Rocky Challenge Makes The $1.9 Billion Movie Franchise Even Better

Although Rocky and its subsequent sequels are now considered classics of cinema, Sylvester Stallone recently revealed his biggest challenge when making the film, and it actually makes the movie so much better. Rocky is a 1976 sports film starring Sylvester Stallone as Rocky Balboa, a small-time boxer that gets the chance to prove himself against the world heavyweight champion. The first film saw great success, and as a result, it spawned five sequels and a spinoff series entitled Creed. Stallone has remained close to the franchise throughout its impressive run.
