OK, when people complain that the film is not in widescreen, they do not know anything about this film or in fact the film creation process. In order for this film to be in widescreen, they would have had to re-make the whole thing (unthinkable), or re-draw the lost edges (impossible). As another reviewer has stated, any "widescreen" version is a fake, they've used simple tricks such as cropping or stretching to fill a widescreen space, there is NO widescreen version of this film because it was NEVER MADE IN WIDESCREEN.
Stunning steady picture quality, the colours and quality of the drawn lines, for a 70 year old movie, is astonishing. The scenery and backgrounds are absolutely brilliant. This is easily one of the best Blu-Ray releases, but I'm biased slightly because this is one of my favourite films ever made.
