Comedy Central’s Stephen Colbert will reportedly celebrate the opening of The Hobbit by bring Middle Earth to downtown Manhattan.

The host of  The Colbert Report will play host the cast of the upcoming movie, announcing the upcoming series during his show on Thursday.

“Elen sila lumenn‘ omentielvo,” Colbert said in his announcement to Entertainment Weekly, the Elvish phrase translating to, “A star shines upon the hour of our meeting.” He continued, “I mean that sincerely.”

Mr. Colbert  announced that he will welcome guests Ian McKellen, who plays Gandalf, on Monday, December 3; Martin Freeman, who plays Bilbo Baggins, on Tuesday; director Peter Jackson on Wednesday; and Andy Serkis, who plays Gollum, on Friday.

The announcement comes as Mr. Jackson has increased advertising ahead of the movie’s opening. Mr. Colbert’s show is seen a  natural fit for touting the movie, as The Colbert Report host is a major fan of the J.R.R. Tolkien series.

“I have never met a bigger Tolkien geek in my life,” Mr. Jackson said during a November interview. “Philippa Boyens is our resident Tolkien expert, and when Stephen came down to visit the set, we put him head to head with Philippa on a Tolkien quiz—and Stephen triumphed. I have to say, his encyclopedic knowledge of Tolkien is spectacular, and points to a deprived childhood in some respects.”

Regarding Mr. Colbert’s cameo, Mr. Jackson has yet to confirm it. Mr. Colbert, who has made no attempt to hide his enthusiasm for the Hobbit series, speaks Elvish, the language spoken by elves in the book, and visited the New Zealand set of the film during production. Speaking at the time, Mr. Jackson neither confirmed nor denied Mr. Colbert’s appearance in the movie.

“I read that, too—it was very, very interesting,” Mr. Jackson said during the same interview. “It’s yet to be confirmed or denied.”

Mr. Jackson’s “The Hobbit: An Unexpected Journey” will arrive in movie theaters December 14.
