Is trouble brewing in Hobbiton? Spies claim "Lord of the Rings" filmmaker Peter Jackson is vexing Guillermo del Toro, who is due to direct the two-part adaptation of J.R.R. Tolkien's "The Hobbit." One insider contends an "exasperated" Del Toro is "tired for waiting" for production to start. "Totally untrue," says Del Toro's manager Gary Unger, who denies Jackson has been holding his client hostage in New Zealand. "Making this movie has been a dream of Guillermo's since he was a kid."
