Roger Ebert pointed to a discussion between
Errol Morris and
Werner Herzog on the sidelines of Toronto International Film Festival. Morris had been influenced by Herzog, and as he says, on first watching a Herzog documentary, his reaction was to exclaim, "I didn't know that this was allowed" (or words to that effect).
Anyway, now Morris and Herzog are talking, Herzog is explaining how reading extensively is important for film making and starts talking about his recommended reading list for his students, and this bit comes up:Herzog: And it contains "The Warren Commission report" which is an incredible piece of literature.
Morris: Fantastic reading.
Herzog: Everybody in here, even people who made films about Kennedy's assassination including .. what's his name, Oliver Stone. Oliver Stone hasn't read the book, hasn't read the Warren Commission report.
Morris: You know that I'm .. You don't know, but I've been planning to do ... it's for me, my version of tales from the crypt, but it's tales from the Warren Commission report.
Herzog: Yes, but it's a wonderful piece of meaning. It's one of those books where you rush home just to continue reading.
Morris: Unreadable!
If you have the time, I would spending the hour of so watching these two talk. The videos are embedded in the link to Roger Ebert's blog given above.
