In an interview with Collider Hugo said,
” I found out The Hobbit was going to be a trilogy quite recently, when everyone else found out about it. Originally, when I said goodbye to Pete [Jackson] in L.A., I said, “I’ll see you on The Hobbit,” and he said, “Well, I’m not doing The Hobbit.” And then, it was, “We are doing The Hobbit, but I’m not going to direct it.” And then, it was, “Well, I am directing it now.” And then, it was, “Actually, we’re doing The Hobbit in two films.” So, when I went to shoot it out there, there were two scripts and two films. Now, I’ve just found out, not that long ago, when it was announced. He said, “Well, we’ve got all this fabulous material and these wonderful people.” They hadn’t filmed the final battle sequence yet, which would have been at the end of 2. For a number of reasons, they decided that there are three films in there. I hope there are. I don’t know. I was truly there for four or five weeks and enjoyed myself, and went home again. My knowledge of the workings of Middle Earth, at the moment, are very minimal. “
The Hobbit: An Unexpected Journey is in cinemas from 14 December 2012.
