well if you think about it, it's shot on film and then usually edited on computer and then transferred to film again.

because it was shot on film in the first place, that's the limiting factor... so i'd have to say their 'resolution' is the same. it also depends on the size of the film grain (so like ISO rating or speed), cause the smaller the grain the more detailed the image gets, but this is all just my opinion. it's like, 'how can the blu-ray have better resolution or better clarity than the film that it came from?'
