I love them. Guest directed:

* Waiting for Guffman (1996) – and played Corky St. Clair
* Best in Show (2000) – and played Harlan Pepper
* A Mighty Wind (2003) – and played Alan Barrows

My favourite still is This Is Spinal Tap where he played Nigel Tufnel.

When the golden oldies rock station plays Tap I turn the volume up to eleven.

TRIVIA – Wikipedia tells me Christopher Guest is married to Jamie Lee Curtis.

New Guest movie is on the horizon > For Your Consideration spoofing the Oscars (opening in November). Ricky Gervais is in this one along with the usual suspects.
