Please see here. Fisher's carefully coordinated media blitz does him no credit. When nothing else worked, he resorted to attacking good faith actors, like the external investigator who he previously touted as a supporter of his claims, because her investigation didn't reach the conclusion he hoped for. As a result, he has damaged his own reputation in a way that is probably irretrievable.
Fisher is going to be blackballed in the film industry, and rightly so. His interview with the Hollywood Reporter showed there was no smoking gun, and there never was one.
