I hope its just a case of workload. These films are exhausting projects for shore, and hes not as young as he was when he worked on Lotr. I thought he had visibly aged quite a bit after AUJ, probably not helped by the need for rewrites due to the changes in the film. The strange thing is that orchestration seems to be such an integral part of shores creative process, so im intrigued as to how this will play out.
