I'm probably one of very few people to own a copy of the hour-long documentary that was destined for the Touch of Evil DVD, but was pulled at the last moment.
It's a good quality recording from BBC2 late one night (there are no adverts), and is split into two halves - the first details the making of the film and the second details the reconstruction, with comparisons and specific examples of the re-edits.
It's very much in line with Laurent Bouzereau's other retrospective documentaries - fairly bland technically and structurally, but very interesting nonetheless.
I'm afraid I can't make any copies as I only have one VCR, but if anyone who can transfer PAL VHS material and has the webspace wants to stick it up on the web, they're welcome to it.
