Gandalf the Grey, the Elves and Gollum are back on the big screen for The Hobbit: An Unexpected Journey, including Andy Serkis who play Gollum.

People are really excited because it's been directed by Peter Jackson who was behind the Lord of the Rings trilogy.

Stars of the film, celebrities and even royalty showed up to the London premier of the movie.

And before all of that Leah caught up with the actors.
