Rocky Balboa and Ivan Drago had a bit of a rematch in a deleted scene from Creed II, and Sylvester Stallone was pretty unhappy to see it hit the cutting room floor.
Perhaps a Rocky Balboa vs. Ivan Drago rematch would have distracted from the feud between Adonis and Viktor in Creed II, but it certainly would be fun to watch.
Ivan Drago was a breakout role for Lundgren, who instantly became a star following the release of Rocky IV.
The two characters duked it out briefly once again in the axed Creed II scene, and Lundgren recently brought it up again at FanX Salt Lake Comic Convention.
