 The version of the film on the DVD is presented in 1.33:1 full frame. Many   people claim the film was shot widescreen. Director Pete Walker shot the   film in a 1.33:1 open matte aspect ratio with the intention of matting the   film at 1.85:1. As the 1.85:1 matting would have eliminated the excess   picture info at the top and bottom of the frame, the film is presented as   shot.
