Making Hollywood's opinions to be more "creditworthy" than anyone else's is a peculiar way of assigning such. Pretending to be someone else and getting paid for it is not a basis to assign "credit" or added weight to an actor's opinion on anything. Good acting doesn't necessarily entitle them to such acclaim. Do you have a rational basis for this "credit" you wish to assign or is it "star power." I grew up on Los Angeles. Perhaps you did too. You know that actors are not exactly ones whose opinions are entitled to any higher credit than anyone else's. Star power ain't brain power.
