Next week is "Hobbit" week on "The Colbert Report"

It's safe to say that comedian and "Lord of the Rings" superfan Stephen Colbert is pretty excited about the Dec. 14 premiere of "The Hobbit." Colbert, who already has a cameo in one of the three "Hobbit" films, will next week host four guests from the trilogy, in what Comedy Central calls "A Tolkien-Themed Week." Ian McKellen, who plays Gandalf, Martin Freeman (Bilbo Baggins), director Peter Jackson and Andy Serkis, better known to audiences as Gollum, will appear on the show from Monday to Thursday, respectively.

It's no secret that Colbert loves the Tolkien series; in a recent interview with Playboy, the comedian admitted he's "a little obsessed." On his show, he's tested the LOTR knowledge of James Franco, Neil Gaiman and John McCain, and forced Elijah Wood to talk about swords.
