The National Geographic Channel is using humor to sell it's ambitious new special Stonehenge Decoded. Christopher Guest has resurrected his Spinal Tap alter ego for National Geographic Channel, lead guitarist Nigel Tufnel, to expound on his theories about how Stonehenge came to be. Naturally, even as he's promoting the special and National Geographic, his tongue is firmly planted in cheek as he disses the findings of the scientists and purports to be an expert on the subject.

Guest as Tufnel is interviewed by straight man -- comic actor -- Jim Piddock, leading to riotous takes by Nigel about dinosaurs, the secret language of potatoes, the pyramids and other weighty affairs. Here's one of the videos (after the jump), so you can see what I mean:

Add Ricky Gervais to the list of cool kids who get to star in Christopher Guest films (This is Spinal Tap, Best in Show, Waiting for Guffman). Gervais, creator and star of The Office and Extras, will make his big screen debut in Guest's new movie, For Your Consideration. It's about the cast of an indie flick that starts to get high hopes when their movie gets internet buzz and rumors fly about possible nominations. The movie stars the usual Guest actors, including Catherine O'Hara, Eugene Levy, Parker Posey and Fred Willard. Gervais and American The Office actor John Krasinski also have roles. Interestingly, Christopher Guest changed up his format for his new movie. It's not his typical, improvised 'mockumentary', but it's being called "a movie within a movie", with lots of scripted scenes. It's the first movie role for Gervais, who said he accepted the part because "Christopher Guest is the single biggest influence on my comedy."

For Your Consideration hits theaters in November.
