Anyone who watches The Colbert Report knows host Stephen Colbert is obsessed with anything Tolkien. The director of the Lord of the Rings and The Hobbit franchises, Peter Jackson, even describes him as the biggest Tolkien geek he knows.

And after countless show dedications to the franchises and a set visit, it appears Colbert finally lived out his nerd fantasy in The Hobbit: The Desolation of Smaug.

It's easy to miss, but Colbert disguised as a Laketown spy has been seen in the film. Colbert was not the only one to join in the fun - his family joined him! His two sons can be seen running across the screen and his wife is shown lighting a match.

The Hobbit: The Desolation of Smaug is the second film in The Hobbit trilogy. It opened 13 December and is still doing well on the box office.
