Stallone revisited his most famous role as boxer Rocky Balboa for a seventh time in the movie written-and-directed by Ryan Coogler, a reprisal he needed to be convinced of.

It has now been revealed Coogler, Stallone and Michael B. Jordan - who plays lead character Adonis 'Donnie' Creed, the boxer son of Rocky's late friend Apollo Creed - shot a trio of contrasting outcomes of the movie's final fight.

A source told the New York Post newspaper: "They shot the ending three different ways ... The way the fight ends in the movie is not how it was originally planned."

The reason for the multiple endings that Coogler could choose to use for his film's finale could be because a sequel was planned during the shoot.

Earlier this week, Stallone revealed a follow-up movie is on the table which could even see Rocky reunited with his former foe Apollo in some flashback scenes, with Carl Weathers returning to the franchise to reprise the role for the first time since 1985's 'Rocky IV'.

Stallone said: "Ryan has some ideas of going forward and backward and actually seeing Rocky and Apollo together. Think of 'The Godfather 2'. That's what he was thinking of, which was kind of ambitious."

Stallone's reprisal of Rocky has earned him a Golden Globe Award nomination for Best Supporting Actor in a Motion Picture, his first nomination at the ceremony since making the original 'Rocky' - which he wrote as well as starred in - 39 years earlier.

The action legend is also being hotly tipped as the favourite for the Best Supporting Actor Oscar.
