People here might find this interesting. In the UK newspaper
The Guardian, on 19th November, there is a reference to a featurette in
The Battle of Five Armies DVD, in which Peter Jackson admitted that, due to Guillermo Del Toro's departure, he '
started shooting the movie with most of it not prepped at all'.
He also said:
“You’re going on to a set and you’re winging it, you’ve got these massively complicated scenes, no storyboards and you’re making it up there and then on the spot […] I spent most of The Hobbit feeling like I was not on top of it ][…] even from a script point of view Fran [Walsh], Philippa [Boyens] and I hadn’t got the entire scripts written to our satisfaction so that was a very high pressure situation.”
