Holy s**t, please let this happen! Nothing is officially set up yet, but there is interest from both sides. Matt Smith said in a recent interview:
"Let's get Peter Jackson to direct one and go and make it in New Zealand. I would love to, I will campaign endlessly to come over and film there."
And Peter Jackson thinks that's a good idea too.
"I'm a huge Doctor Who fan, and I think Matt's fantastic. Just name a time and place, and I'll be there!"
What kind of episode do you think Jackson would direct?
"In a hole in the ground, there lived a hobbit." On September 21, 1937, J.R.R. Tolkien published The Hobbit. 75 years later, we're still reading about that hobbit who left that hole in the ground to follow a band of dwarves and a wizard on a great adventure. The children's novel has been translated into more than 40 languages, sold tens of millions of copies, and has been made into an upcoming movie trilogy. It even had a series of sequels you may have heard of.
Thanks for years of adventure, Bilbo Baggins. Happy 75th Birthday!
