The director went on to speak about needing three parts to engage the complexity of the story.

"I was also acutely aware that there was going to be, ultimately, when this cycle of releasing a movie each year is done, you're going to end up with six films. The Unexpected Journey being the beginning and the Return of the King being the end.
