In the decades since the first Rocky movie came out, the franchise has shown the kind of rare staying power that Hollywood dreams of.
According to Irwin Winkler, the reason Rocky has found such success is because the franchise has continued to deal with the real-life issues of the day.
The Rocky series continues to be seen as the ultimate underdog tale, featuring the struggles of small-time boxer Rocky Balboa to become a champion on the world stage.
Rocky came out post-Vietnam War, Watergate etc and in the great era of American dissatisfaction with oneself and what was going in the US.
