The biggest problem with going from computer to film is resolution. 640 x 480 (72 dpi) 
or any close multiple thereof is, in my view, going to look unacceptably "grainy," 
aliased and just plain "low-res."

Here's the good news: The better imaging devices are now able to put 8,000 to 16,000 
dpi onto the emulsion, which is just about the limit of resolution of the film itself. 
They are expensive, but far less expensive than they used to be.

Here's the bad news: you need to provide files with this high level of resolution to 
the machine. This requires you to work in an environment encumbered with high rendering 
times, and deal with image files which are bernoulli sized. This is, however, what the 
film-makers do with their computer generated composites and special effects, and what 
the animaters do when dealing with high definition computer generated imaging.

Hope this helps.
