I would like to see it for sure. Considering that the Lord of the Rings trilogy was one of the highest grossing trilogies at the box office, I'm not sure why Peter Jackson would have any reason NOT to make this movie. Considering that most LOTR fans will see the Hobbit, they are guaranteed to make money.
It would also be really cool if they got the same actors for each character.
I've never read "The Hobbit" though. What is it about really, and is it something that would make a good movie? Does it have a strong plot line?
