Well, EW has put the rumor swirling around a potential Colbert cameo directly to Hobbit director Peter Jackson—and Jackson isn’t denying it! Then again, he isn’t confirming it. “I read that, too—it was very, very interesting,” Jackson says, laughing. “It’s yet to be confirmed or denied.” Jackson will, however, confirm one thing: Colbert is a serious Tolkien fanatic: “I have never met a bigger Tolkien geek in my life,” Jackson says. “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.
