10. Rocky Balboa
Struggling actor Sylvester Stallone got the idea for ‘Rocky’ while watching Chuck Wepner challenger Muhammad Ali for the world heavyweight championship in 1975.
On screen, they morphed into Rocky Balboa and Apollo Creed respectively.
No-hoper Rocky lost a close decision in the first fight – more importantly, he got the girl – won the rematch and the films became progressively worse . . .
