Thank God for Christopher Guest. Anyone who loved him as Nigel Tufnel in Spinal Tap and has since appreciated his mockumentaries "Waiting for Guffman" and "Best in Show" should take a look back at The Big Picture. As with his other films, the humor is subtle and a bit "inside," but the more you see it, the more you love it. Kevin Bacon and J.T. Walsh are perfect, and Martin Short steals every scene he's in. (Added bonus: the Pez People song at the end, obviously sung by Michael McKean, sounds like Spinal Tap with keyboards instead of guitars. Very funny.)
