Tolkien's vast imagination.
'The Hobbit' of course!
I'll assume you're referring to the movie - they ended it because the story will continue in a second and eventually third movie.
Radagast the Brown was an add in. He was only a brief mention in the books, and was never fleshed out into a character. In the movie, Radagast had a strong resemblance to another book character, Tom Bombadil. Tom Bombadil never made an appearance in The Hobbit.
The hobbit comes out on December 19th 2012.
Ralph Bakshi created an animated film based off The Hobbit. Rumors are going around now that Peter Jackson (director, producer, and writer of The Lord of the Ringsmovies) is working on a new movie for The Hobbit, maybe even two. It is rumored that they will be coming out in 2012.
In the book The Hobbit, there is no Elven lady. In the movie, Galadrieal makes an appearance.
Read the book, it's better.
Yes, Frodo Baggins is a Hobbit. In the book he is the main character but not really in the movie.
In the movie he was, at the meeting that was held in Rivendell. He was not in the book though.
It shouldn't be. The publisher is just trying to take advantage of the movie for marketing purposes.
It is going to be filmed at the same time as another Tolkien based movie (I can't find what it is, perhaps something from the Tolkien Reader?) and The Hobbit is going to be released in 2011. Based on that, I would suspect filming is beginning very soon.
The book was based on a dream, and the movie was based on the book, so yes, the book and movie were based on one dream of Stephanie Meyers.
No, but they did make a movie based on the book (The book came first).
It's not based on a book.
There is no movie based on the book Rules by Cynthia Lord.
'The Hobbit' of course!
The movie, Eclipse, is based on the book, Eclipse.
