Caporegime
35mm film is something like 10 mega pixels+. In any case, a blu-ray is a pale imitation of the cinema.
And this is coming from someone that is an avid lover of home cinema, with a projector, surround sound etc.
Proper film can't even really be measured in megapixels, as the chemical process is too "fluid", too analogue. It doesn't really operate in terms of pixels.
