For the first time, the director and co-creators of This is Spinal Tap provide the full behind-the-scenes story of the making of the groundbreaking mockumentary.

Since its original release in 1984, This Is Spinal Tap has evolved from a beloved cult film into an all-time comedy classic. It pioneered the mockumentary genre and is one of the most quoted movies. Now, Reiner, Guest, McKean, and Shearer share clever and stupid tales of their famous collaboration – how the fictional band Spinal Tap came to be and how their low-budget indie film took on an unexpected life of its own. 

Featuring never-before-seen photographs, band memorabilia and personal reminiscences of their enduring creative partnership, A Fine Line Between Stupid and Clever will delight Tap heads of all ages.
