In regard to Lord of the Rings, I'd heard that there were several errors in the film. I didn't see any when watching the movie, and I'm usualy pretty good at spotting stuff like that. Blixx & Grips have taught me way too much about how movies get made for me to miss blatant errors in continuity. Check out Movie Mistakes for a whole big long list. I think some of them are BS, but Blixx asked me to research this so here ya all go.
