Well, well below the 1080 available on digital home systems today. It is a well-established scientific fact that audiences are unable to distinguish film from digital in a theatre.

The lines of photographic resolution on a negative mean very little when you record it on analog film, copy it, and project it on a screen that people are sitting a large distance away from.

1080 is not the upper limit of HD, nor is it the likely format of a professional film-maker. Ultra-HD is widely available and offers 4520 lines of resolution.
1080 is not the theoretical limit, but the practical one.
Next step is 2000p, but that is hardly nessesary.
As for ultra HD WHAT PLANET ARE YOU FROM?
I read somewhere about this, and its so pie in the that a lot question whether it will be used in the forseeable future.
And I dont know where you get the 875 line BS.
Film resolution is dependent on grain, sometimes the film elements are microscopic,
wheareas resolution on a video display is limited to the size of the pixels.
There is no such limit to film.
