Sylvester Stallone has gone in hard on Rocky producer Irwin Winkler after being left out of plans for an Ivan Drago spin-off movie.
The Hollywood actor, 76, was the star of the hit boxing franchise, but is far from happy at one of the OG producers' decision to create a new film surrounding the origins of one of its hit characters.
It's the second time Sly has took aim at Irwin, who helped make the franchise a huge success.
