The Fellowship of the Ring, the first of Peter Jackson's Lord of the Rings trilogy, was released in the United States on December 19, 2001. That means the trilogy is marking its 20th anniversary this month. That movie was followed by The Two Towers and The Return of the King, released in 2002 and 2003. In honor of the occasion, Stephen Colbert (who is one of the world's biggest Lord of the Rings fans) and musical director John Baptiste performed a rap song about the trilogy. And there were surprise cameos.

Yes, those participants included Elijah Wood, Sean Astin, Billy Boyd, Dominic Monaghan, Hugo Weaving, Andy Serkis, Orlando Bloom, and Viggo Mortensen. They were joined by Method Man, Killer Mike, and Anna Kendrick for good measure. A good time was had by all.#TheLordoftheRings&nbsp; #StephanColbert #castreunion #rap&nbsp;
