I don't believe that modern film-makers can frame their shots any longer - making pointing a necessity. Why? A film-maker can no longer know what aspect ration the viewer will see the fim in - whether on a standard movie screen, a 4:3 aspect ratio traditional television, one of the various wide-screen DVD formats, or HDTV. The film-maker simply cannot know where the edges and corners will be. The only thing imporant becomes the center, which will be in the center in all formats, so pointing is necessary.
We don't have that problem with large format photography - we know (if we care to know) where the edges of the print will be at the time of exposure.
