I could go on about this... Nick's covered most of it.

The one other point I'd bring up is that movies aren't just shot, cut and delivered. Film doesn't have a "resolution" per se, it has a frame size and a grain size. The bigger the frame (IMAX vs 8mm, anyone?) and the tighter the grain on the stock, the better the result. By the time all the layers of editing (wire/rod removal, rotoscoping, matting, CG effects, digital painting, etc) are done, it's not the same animal.

Take an extreme case. I'm shooting "the Good, the Bad and the Ugly"... I have a long shot of Clint grimacing, in post I realize that, oh hell, it would be insanely cool to push in on Clint's face - forehead to jaw. Shot digital, I'm probably looking at a 320x180 portion of the image. Shot on film, I'm looking at probably an 8mm x 4.5mm portion of the film (depending on gates, film format - Super 35 or Panavision, etc)...

While the film may get grainy and soft and look like what it's become (8mm film), it will still appear better than the 0.06 megapixel digital shot.

That's an extreme case, but you get the idea.
