Something that Ayn Rand said about making movies out of her books, in order to tell any story Hollywood has to have artistic license to change it and that takes it into a different direction - which I understood happened in the 40's with either the Fountainhead or another movie.

Have you read Fountain Head by Ayn Rand?
When I joined "Audible", I selected "Atlas Shrugged" as my first free book. It's 54 hours long. I've listened to it twice now. In another few months I'll listen to it again. It's ageless.
