Yeah, it's more likely to be from the theatre than the print, but I'm not totally qualified to say for sure. Maybe it's a combo of both. You always get some cropping from the screen, so even if the print itself is cropped, it won't be quite as bad as it looks here. As for using this for a restoration, it's unlikely that whoever owns this is interested in doing something like anyway, or has the means to do so. In any event, a cropped version of the film is what we have been watching all along anyway, this cropping, if you can imagine more picture info existing around the borders that the curtains are framing a bit, is close to many of the previous telecines.
