"Atlas Shrugged" is way too deep for the average movie goer.
I've been a fan of Ayn Rand all my life. I actually think "The Fountainhead" is a better work than "Atlas Shrugged". It's a smoother read and the frustration of the individual is demonstrated better...IMHO.
For those who would like to see the range of Rand's mind, I recommend a small book entitled, "Anthem". It was written way back in the 30's and is very conceptual. It will scare you with its prophecy.
As an aside, I retired from an executive level position where I had many people working for me. I used to give newly hired managers two totally unrelated books..."Anthem" and "The One Minute Manager". Both are fairly old and very short "reads". It was easy to see who actually read them and who didn't.
