There are different types of "producers" - such as Executive Producers, Line Producers, Associate Producers, etc. Your definition there lumps the duties across all these different types of producers into a single description.

Mnuchin was an Executive Producer - that's the only job description that's relevant to the conversation. And again, he was NOT an "Executive Director" as the OP claimed in the title of this post and based the whole thread on that misinformation.
