That's an interesting idea, and I think that it reveals an important aspect of the copyright system. If they had to submit an annual fee for each work, it would be a massive number of things to pay a fee for. For example, if Disney wanted to submit their fee for Cars, would they also need to submit a fee for the likeness of each character, i.e. Lightning McQueen, Mater, Doc, Sally, etc. What about the artwork associated with each of the settings? It's interesting to think that each of these elements is individually protected under copyright laws.
