Below is a rare outtake from Rocky IV directly from Sylvester Stallone himself. Stallone is preparing a director’s cut of Rocky IV and can be seen working on the project in the video. This stuff is like gold dust, extras for the fourth film have always been thin on the ground.
Personally, I would like to see this begin a new trend with Stallone films. I mean, I’d rather see a longer version of Rambo II (if it exists) than a new Stallone film, probably. First Blood is another movie that has various very long cuts lurking around in archives.
