Interestingly the book and the film were developed together by Kubrick and Clarke as a collaborative process.
Usually the book comes before the film, but occasionally it comes after.
I can't think of other examples where the novel was developed alongside the film but I expect there are!
Game of Thrones?
Because it's either:
A) regular Hollywood schlock that ruined the last seasons; or (worse)
B) that was his actual direction for the book series and now he knows that it's not good.
Either way, I believe we will never get the final books in that series due to the television series.
However, they should hire writers that can actually write characters and plots other then simplest ones. The writing quality was indeed horrible by the end.
