Peter Jackson figured out how to do this - filmed three movies back to back from what I recall. The Rings movies were followed up every year around year's end for three years straight. And each part of the trilogy was kept in the cinemas too for the entire year until the baton was handed off to the next one.
I guess RoP did not have the script in place to even attempt to do this.
Still can't wrap my head around how they spent 700 million (going by that article) including rights on this one season. I know it's supposed to contain around 250 million or slightly less for the license but that still leaves around ... 450 plus for 10 episodes? Is that like 10 times of what an average GoT episode would have cost.
Always thought the 1 billion overall budget was meant for all the seasons plus the rights and probably for setting up a TV show division within the company on the back of this production. Now it turns out they are leaving NZ for the UK and that seems like it wasn't even factored into the 700 million already spent?
That must have been a lot of first class flights to NZ and back.
