Some of the scenes that were cut for the PG-13 rating, but were never put back even in later DVD and Blu-ray so called R rated versions of the film, include lots more blood in all the Rollerball scenes and parts like skulls getting smashed, bones getting broken, teeth flying out, a scene where Aurora is topless and walks towards Jonathan in the locker room originally didn't have a shadow over her (this was added in post production to cover her up for the PG-13 rating), their sex scene was also longer, and so was their conversation while they are lying down in a sauna. Some of the other similar edits that were done on more graphic scenes in the film include digitally replacing blood spurts with sweat.
