"To insist that a storyteller stick to the facts is just as ridiculous as to demand of a representative painter that he show objects accurately. What’s the ultimate in representative painting? Color photography. Don’t you agree? There’s quite a difference, you see, between the creation of a film and the making of a documentary. In the documentary the basic material has been created by God, whereas in the fiction film the director is the god; he must create life. And in the process of that creation, there are lots of feelings, forms of expression, and viewpoints that have to be juxtaposed. We should have total freedom to do as we like, just so long as it’s not dull. A critic who talks to me about plausibility is a dull fellow."
Alfred Hitchcock talking to Francois Truffaut about THE 39 STEPS.
The 39 Steps is a film having far too much fun scrambling from one great moment to the next to have time for trifling things like “plausibility.”
(page 102 of Hitchcock / Truffaut, which is as essential a film book as has ever been published).
