Hail, Caesar! is about, in my opinion - I love that movie - but I think it's about the idea that as glamorous as the business is, and for as much hoopla that surrounds moviemaking, ultimately it's just a job. If you focus on it, you can do it really well, and it takes a lot of hard work.
I have never had a problem dealing in areas of ambiguity. I can make a decision and not have it all lined up just right.
