Fake 'Widescreen'
Mill Creek included this in their 50 Movie Collection which at first appears to be "Widescreen" but if you carefully watch the top black bar during the lighter scenes you can see faint shadowy images caused by the portion of the picture that were blocked off by the bar. The only possible reason I can think of why this was done would be to fool the consumer into thinking that this DVD was an impressive, special "Widescreen-Letterbox" version.
