Why is Barry Munitz in this film? A follow up documentary?

Why is Barry Munitz in this film? He resigned after taking a million dollar salary, numerous other questionable perks, and losing more than $1Billion in the stock market from the J. Paul Getty trust. Is he really an authority for proper management of trusts or is 9.14 planning a follow up documentary on him? It would be even more explosive than the Barnes Foundation. Still scratching my head why he is in this film.
