8. This Is Spinal Tap (Rob Reiner)
Cult classic This Is Spinal Tap written by director Rob Reiner and stars; Michael McKean, Christopher Guest and Harry Shearer may be a satire on the rock band but its one of those great Hollywood scripts full of endless gags and superb characters. This comedy started the careers for those writer/actors and paved the way for a new subgenre and many icons of the medium including The Simpsons. Like Borat it may be a fantastical, fictitious story but it still highlights the thoughts of these great actors in the 80s as they encapsulated everything wrong (and a lot of the right) about rocknroll.
