Most films have their actors sign a non-disclosure which prevents them from talking negatively about the film. Non-disclosures typically expire in five years, depending on how they are written. If an actor talks poorly about the film during that time, they risk severe legal action.
You won't hear him say a negative thing about it I'm afraid.
Again, it's not his movie. And he's friends with those actresses. I doubt he'd go around bashing it just to placate some over grown children online. Stop trying to make him your hero.
