This Is Spinal Tap
Director: Rob Reiner
Cast: Christopher Guest, Michael McKean, Harry Shearer, Rob Reiner

A brilliant rockumentary about an over the hill British Heavy Metal band who take their last shot at fame. This influential comedy has hilarious parody on show business, amusing music and lyrics, and great comedy set pieces. Christopher Guest, who plays the lead guitarist Nigel Tufnel, has subsequently made a career out of similar type of comedies (for example, Waiting for Guffman and Best in Show).
