Film still currently beats digital. However 4000 x 3000 pixels is ample for movie production and print etc..
35mm and above like 85 mm cameras can take stunning quality results. Usually reserved for high end shots for compositing or for artistic endeavors. Ive seen shots that large used for portraits and backdrops in movies etc..
35mm SLR is still used by certain photographers, but with the advent of 10 mega pixel cameras and above the quality is suitable for most industries in print & design etc..
If you have an digital Iso 1600 camera like me you can capture amazing shots in total darkness on a digital camera. It looks like twilight, very magical, no noise problem. However that is due to a high end Canon Digital SLR.
If you can remember the movie tron as well it was shot on huge cells and many layers of them, up to 50 in some scenes, when it was being procesed in korea they stuffed it up a bit by not letting the film dry and hence, light smears appeared on the film composition, so they added sounds to the movie as if it was rogue bits flying around.
My Xgf is a professional photographer and she has a few digitals but also linear film based ones. The most interesting is a very expensive massive german camera with virtually a4 sized film, the results are stunning. She has to stand under the black cloth and the results are upside down on her viewing screen. The actual film is huge and produces amazing results.
The best way to move this into a digital realm is with a drumroll scanner, but who has $100000 for a basic one and the time it takes to apply the photograph to the roll while making sure there is no bubbles between the photo / oil and clear wrapped plate.
If you process film, dodge and burn in photoshop will make a lot more sense, that said however you can get sick if you spend to much time in dark rooms with all the chemicals.
Plus its a very expensive process to sticking a memory card in your reader or attaching the camera to the computer.
Think of film as linear with no undo
It would be funny if we still called them Heliographs or Daguerreotypes. Imagine also having to sit still for minutes just to get the shot.
