I wrote my thesis in film music. One main conclusion I came up with: there are rather classical trained composers and rather "pop music" composers. E.g. the latter one need many orchestrators for the score, the "classical trained" ones orchestrate on their own. To me the popish ones might be able to have good ideas, whereas the classic ones do have such ideas as well and be able to know exactly how to craft those ideas as well.
Zimmer is a popish one, while Williams a classic one.
