The rights to a movie adaptation for all of the Shannara novels have been sold to Warner Bros until 2010. The Elfstones of Shannara, the first planned movie, will be filmed and directed by Mike Newell, who was also responsible for Harry Potter and the Goblet of Fire. The Elfstones of Shannara will probably be followed by an adaptation of The Sword of Shannara in 2010 or so. Note that the sequence of the movies differ from the sequence of the books, although Terry Brooks believes that this is the best starting place for adapting the Shannaranovels.
No there isn't one planned yet. The Warner Bros. company bought the rights from Terry Brooks in the 2000s but they lost their rights in 2010 because the person Mike Newell was going have it filmed and directed but he left the project. Right now there is no official word on which movie company is going to own the rights.
Maybe Warner Bros. company will buy it back or Disney or MGM or Universial Studios or Fox studios. Hopefully they'll do a good job on the movie adaption. But if there's going to be a movie adaption whether it be a cartoon or live action, there will be changes made in the movie similar to the live action "Lord of the Rings" 2001 remake and "The Hobbit" 2012 remake. Hopefully this answer will be updated and we'll get an official "Sword of Shannara" movie anoucement.
The vorpal sword
Before Anduril, he was using ranger sword.
The bandersnatch is the guardian of the vorpal sword in Tim Burton's 2010 movie, Alice in Wonderland.
The Hunted
It seams unlikely
The Sword of Shannara was created in 1977.
"The Sword of Shannara" by Terry Brooks has around 726 pages in its standard mass market paperback edition.
Warner Bros (who owns the rights to the series) will not make a Shannara movie until after the established series they have are finished. Harry Potter ends its run the begining of next year and now that Warner Bros has begun production of The Hobbit you can expect Shannara to be shelved for at least another few years. IMDB has the listed release date as 2013 now.
