Film maker Costa Botes pointed out a gaffe in my review of his “LOTR Behind the Scenes” documentary. Five years of filming on set produced not 21 hours of footage, as I’d said, but 800 hours, from which he “cut 21 hours comprising 180 stories on every aspect of the production. And from that 21 hours (leavened with extra footage so that anyone who ever did get to see all the 21 hours would still find something fresh) we cut the final three feature length docos.” Makes you wish, doesn’t it?
