What is there to say about the legendary Spinal Tap? Only that it's the funniest, most revered film ever made about rock music. A true cult classic, Spinal Tap is celluloid satire at its finest, as the imaginary heavy metal band take on the music business under the watchful eye of a TV documentary crew - with priceless results. Made in 1984 by Rob Reiner, legal wrangles have meant it has been stuck in commercial limbo for more than a decade. However, fans are now able to tap into what made the film so brilliant. The book is packed with exclusive material, including the illustrated screenplay, movie stills, contributions from the band members and extracts from improvised footage that never made the final cut.
