If Mia Farrow, who is certifiably nuts, were to ever admit that Ronan Farrow is the biological son of Frank Sinatra, she would lose her moral authority as the aggrieved party in the whole Woody Allen mess. Everyone knows this.
The rule of thumb is, you stay away from these people as far as you can; if you're an actor with a certain amount of vanity, you're allowed to go do your one Woody film so that you can have credibility. The rest of them, ugh. Nothing is worse than a blog post that mentions these people, not even a story about some jackasses who drowned a dog because they were doing donuts on the ice.
