Ah, the sound... where to begin? Well, before the film starts a message informs you that the sound was recorded using a binaural system, so that it is heard from the perspective of the lead character. This meant that sometimes the sound was 'flipped' from the direction of the action onscreen. A pair of miniaturised radio microphones and transmitters was built into the wig worn by Nicholas Hope to record the sound in this type of stereo. It certainly gives you an unusual listening experience to say the least, and is definitely worth sticking on a pair of quality headphones to experience it fully. In some scenes when the camera pans showing Bubby's POV the sound panning is very immersive indeed. The whole 5.1 Dolby Surround mix is lively with plenty of separation, although it is mainly front and centre oriented and there's not much bass evident. The dialogue is always clear, even with excessive competition from music and ambient effects. Very often a plethora of things is going on audio wise but even with the dialogue, a crowd cheering, a 'live' band playing and the score all cross-fading at once everything is distinct with no peaking. It's a great mix.
