Huston: 'Under the Volcano' isn't a great book.
I don't recall exactly which of the Criterion special features included this comment (some sort of radio interview?), but it certainly took me by surprise. I'm a great admirer of the novel, and I have a growing fondness for the movie, but I fail to see (a) why Huston would deny the book's greatness, and (b) what would make him, in that case, interested in filming it.
These questions were probably answered by the man himself -- but I haven't watched the DVD in a while, and I just wondered if anyone else was startled by the man's comment.
Incidentally, if you don't own it already, the included Lowry documentary alone makes it well worth purchasing. Listening to the great Richard Burton read from the man's work almost makes me wish he had been available for the part in '84. Of course, then we wouldn't have Finney.
