I was apprehensive about hearing Blatty spout all kinds of socio-psycho-religious fluff throughout this commentary, given the scrambled nature of the movie, but, refreshingly, he keeps on track with several anecdotes and insights into the making of the film and the circumstances of its MANY different versions. Kermode is a worthy co-host on the track - he obviously knows his stuff about the film and primes Blatty with intelligent questions throughout. Together they smooth out all the confusion of the different versions of the movie (and the book) by mapping out deleted and reshuffled scenes that explain the characters' motivations and the primary theme of the movie.
