When you are a Hollywood celebrity, like these featured in this documentary, you are not permitted to ask questions--the kind that can threaten those in your circle who manage your career. Notice that the more celebrities use their platform to promote agendas--especially truth-telling ones--the more likely they will be a target for all sorts of mayhem. Some of which include: peer pressure to drink, use drugs, attend wild parties (where a celebrity's morally offensive behavior is recorded then later used against him or her), stalked, threatened, a loved one murdered, etc.
Celebrity superiors/owners don't want the masses to know the truth about anything (particularly government related) unless the exposure of information benefits them in some way i.e.) more products sold, name recognition, status, etc. The celebrity is used, like a pawn in a game, to deliver only what his or her handlers want you to know.
Never believe you are getting the whole truth and nothing but the truth from someone in mainstream media or a has-been celebrity--it doesn't matter if he or she is an actor, musician, politician, educator, lawyer, dancer, or a one-hit wonder. Oftentimes, those old names, that were once popular names, resurface when there is a temporary job to do--usually to distract the masses, sway public opinion, or fatten someone or some group's bank account, then they quietly fade out again until the next opportunity.
