Not the best mockumentary that Christopher Guest has appeared in, but it certainly deserves points for being the first. "This is Spinal Tap" proves a fitting satire, equal parts tribute and send-up, of Eighties rock excess, all the more impressive considering this kind of hair metal was still en vogue at the time. The scene in which Guest complains about the catering is one of the funniest moments in cinema history.
Doesn't seem to matter how many times I see this, it never loses its capacity to delight and make me laugh out loud. The secret ingredient, I think, is the genuine affection that each of these amazing actors has for their created characters. There's a wonderful benevolence that runs through the entire piece alongside the beautifully realised tropes. It rocks.
