Christopher Guest deserves to be sleeping with Jamie Lee Curtis. Hold on. Let me explain.
   He helped invent the "mockumentary" back in 1984 when Spinal Tap was released but perfected the genre in the late 90's with Best in Show and the classic Waiting for Guffman.
    The film centers around a play that's being developed by Corky St. Clair (Guest) for the bicentennial celebrations in Blaine, Missouri. What makes this movie so special is the way in which it was scripted - it wasn't. With the exception of the actual play, all of the film's dialogue was improvised on the spot.
    They'd script a simple outline, flush out a few ideas beforehand and just let the cameras roll. A big risk some might say, but the film was low budget and the cast was up to the challenge. With alumnus from SCTV and SNL making up a majority of the players, this sort of improv was second nature. Watching the film, it's really hard to believe they were able to pull it off with such hilarious results.
   Corky is as gay as an Easter parade, and in possession of about as much natural talent as Tom Arnold. Actually, strike that. I've grown to like Tom Arnold over the years. Anyways, a seldom publicized tagline for the film reads, "There's a reason some talent remains undiscovered." The play's performers, hand selected from local townspeople via a rigorous audition process (you have got to see the 80 year-old man reenacting the "Did you fuck my wife?" scene from Raging Bull,) are almost worse. But somehow, they pull it off and attract the attention of an agent from New York who promises to take them off-off-off Broadway. The movie has become a classic and is so full of subtle jokes, you'll have to watch it 10 times before you catch them all. Don't wait for Guffman any longer.
