Christopher Guest has to be the most successful mockumentarian to date. The competition is pretty thin, but the caliber at which Guest has been performing since way back with This is Spinal Tap sufficiently distances him from all comers. While he has written and directed at least three phenomenal entries to the genre, the endless number of bizarre, captivating, charming, endearing and thoroughly unique characters he’s devised easily earns him a spot at the top. To put it more plainly, Christopher Guest is to mockumentaries what Julia Child is to TV cooking. Or to put it even more plainly, Christopher Guest is Julia Child.
