Let me expand on this a little. First, you’re right about some of the ad posters of the time being in colour; however, this cover looks rather shoddy. If anyone has this blu ray and can explain its shoddiness, please let me know. Second, sometime in the last century (probably in the '70s or 80's), black and white films were colourized in order to bring more revenue from studio libraries and apparently the public responded to these. Needless to say most filmmakers were not too happy with this (Orson Welles apparently pleaded a few weeks before his death for Citizen Kane not to be defaced with crayons) In this millennium, thankfully, there's an appreciation for black and white films and its art form. I may be a little sensitive to colour representation of black and white films as I really love the art of black and white films and it would be great to see them be celebrated as such.
