This remix of the original monaural audio expands the image in a modest but pleasing manner. Most of the sound remains anchored to the center channel, but a few effects spread nicely to the sides as well. The surrounds also include these factors. The effects pop up from the rear mainly during the final fight scene, but the music drifts back there quite frequently and it adds a lot to the impact of the score. Quality seems decent but unexceptional.
Dialogue appears vaguely flat for the most part, but it remains consistently intelligible and clear.
This wasn't an issue at other times, though. The 5.1 mix stays appropriately modest and it works nicely for the film. Very few of them include substantial supplements, and Rocky falls into that category. We find the film's theatrical trailer, and that's it. The DVD itself offers fairly good picture and sound although it skimps on extras.
