I saw on the other thread that you all were talking about mistakes in movies. Here is the address for the best movie mistakes website I've ever seen. It has an enormous collection! www.movie-mistakes.com
Been there. I've submitted to them a few times, but they haven't posted any of my movie mistakes. I lean towards nitpickers.com, myself. Their database is enormous, and the members themselves vote to decide which nitpicks get posted, which helps to cut down on all the erroneous movie errors submitted.
