There is no hard and fast number for pixel resolution of film. For 35 mm film, I have read effective pixel resolution is as high as 5000 by 3760, although I have also read that a projector may put out around 3500 by 2000. Roughly, then the range is about 7 million to 19 million pixels required to capture a 35 mm image.Now HDTV has around 2000 by 1000 pixels. And NTSC video is 720 by 480 pixels. In NTSC, a big chunk of the image is chopped off due to the different aspect angle, but in any case, optimistically, you are left with somewhere under 5% of the information. And HDTV, while quite a bit better, is still missing 3/4 of the visual resolution.
Not to mention that you can see hundreds of movies, maybe thousands, for the price of an HDTV.
