- Extra thunderclap sound effects were added in the scene when David and Jack are walking in the moors and it starts to rain.
- The first werewolf can now be heard growling in the rear channels as it circles David and Jack. A louder growl has been added to the rear-left channel after Jack says "It's circling us" to make the audience jump.
- All the gunshots and car crash sound effects have been replaced.
- The train in the "London tube" scene can now be heard moving from one channel to another
- Despite the improvements, the music throughout is inexplicably mixed down a half-pitch and sounds very different from the original mix.
- All earlier releases of the film including the initial 2-disc 21st Anniversary Edition are uncut. Universal Studios issued a statement saying that they will remove all affected stock and issue replacement discs. All Blu-ray releases are complete and uncut
