The Dark Knight has black bars that come and go, due to the occasional switch to IMAX. Again, though, this isn't a case of them randomly 'adding black bars' to the original footage, it's about them maintaining the original aspect ratio within the confines of a 16:9 television screen.I'm not a fan of artificial letterboxing, myself. We did it on Extraction Protocol and I rather wish we hadn't - ultimately it just results in lost pixels without much in the way of dramatic gain.Edit: Yeah, that is a good example, Stormy. Pan&Scan was an is a horrible, horrible technique. It introduces new, artificial, flat camera moves, destroying the original intent of the cinematographer.
