Plenty of films of this vintage suffer from boom mikes in frame and the top and dolly tracks visible at the bottom: this is an artifact born of failed productions. When the camera operator composed the shot, he had been told the film was being made for theatrical release, in a 1:1.85 ratio and so when the boom dipped down slightly, but not enough to make it into the "letterbox" they let it slide. Then, after the film failed on the festival circuit or preview process, etc and was dumped to video no one cared to correct the errors - they were all just trying to dump the project on the market as quickly as possible. Had the final "release print" been made, instead of a video transfer from the camera original (mivees and all) we would have been spared the spectacle of seeing mister boom mike. Most of these types of film were being dumped onto the video market before consumers cared to see letterboxed releases, so the transfer was made full frame.
