 The entire film was shot in digital except for the final shot, which was  filmed using the same Panavision camera featured in the movie. Director  David Cronenberg (qv) assumed that audiences would easily be able to tell  the difference, but as it turns out, most of the people in the premiere  audience didnt notice the switch. For subsequent screenings, Cronenberg  added music to the shot to give it additional emphasis, although audiences  still had trouble.
