Rocky Balboa remains Stallone's most important role, and his first outing as the plucky pugilist saw his stock rise dramatically. Stallone was instrumental in creating Rocky, as he penned the script as well as bringing his own unique brand of brawny charm to the downtrodden boxer who gets one shot at glory in a championship bout.

The film received 10 Oscar nods (with Sly recognised for acting and writing) and took home three, including Picture and Director.

Tough Guy? He proves his mettle by pummelling meat carcasses and going 15 rounds with Apollo Creed, before revealing a soft centre by declaring his love for Adrian.
