Actors Improvised These Famous Moments In Cinema

This Is Spinal Tap

Often called one of the funniest films ever made, This Is Spinal Tap had so many improvised moments that the actors are credited as writers on the script! The mockumentary relied on the chemistry between the castmates as they riffed off each other.

The result is clear: a natural and hilarious film that feels real even though it is entirely fiction. Decades later, it is responsible for paving the way for more mockumentaries and creating a whole new genre of film and television.
