Elijah Wood has dropped a few hints about the first Hobbit movie - saying the new film will have characters that aren't in the book.
The star, who will be reprising his Lord Of The Rings role as Frodo, said he has seen the script for the first of the new Hobbit films.
He told The Hollywood Reporter: "I read the first script and it's incredible.
"It definitely expounds upon the book; there are already characters that are cast that are not in the book, so that indicates that it goes slightly outside the boundaries in the structure of the original novel."
Elijah said filming his scenes for The Hobbit: An Unexpected Journey, in the autumn in New Zealand, would be like going back to a giant family reunion.
The star told The Hollywood Reporter that he hadn't seen the script for the second Hobbit film and that he had no idea how Peter Jackson's big-screen adaptation of the JRR Tolkien novels ends.
Other Lord Of The Rings cast returning for the Hobbit films include Sir Ian McKellen, Orlando Bloom, Andy Serkis and Cate Blanchett.
The 30-year-old, who is currently appearing in FX comedy Wilfred, returns to New Zealand in autumn. He will be joined in The Hobbit movies by Lord of the Rings cast members including Orlando Bloom, Hugo Weaving, Cate Blanchett, Andy Serkis and Sir Ian McKellen.
New cast members in the Peter Jackson-helmed production include Stephen Fry, Evangeline Lilly, Barry Humphries, Saoirse Ronan, Aidan Turner and Richard Armitage. Martin Freeman plays the lead role of Bilbo Baggins and Sherlock co-star Benedict Cumberbatch will voice Smaug the dragon.
The Hobbit: An Unexpected Journey is scheduled to debut worldwide on December 14, 2012. It will be followed by The Hobbit: There and Back Again on December 13, 2013.
