The 35mm film used for movies gets about 8K (about 128MPixels) at 
maximum. This is for a VERY slow film (about 100AZA) which is not 
usually used in movies.

The more popular 400aza one gets about 4K (32MPixels)

Scans from film to digital media are done at 8K nowadays (telecine).
Special effects are usually rendered at 4K for big budget films and 2K 
for more "average" budget films.

The main difference between film and digital imagery is the way the 
pixels or grain are distributed.
Pixels are evenly distributed, which usually creates some artifacts 
when it comes to hard lines in the picture.
Film grain on the other have is randomly distributed, which gives it a 
much more real feel on lower resolutions.
Having this in mind, I would say that film used for most of the movies 
can only be beaten by a 8K raw digital camera footage.
