[on working with Alan Alda] If I wanted a sermon I'd go to church. He just wouldn't quit. He just kept adding more speeches and more moralistic stuff. After he got famous, he got really pompous. He started thinking he was speaking God's words--not the lines in the script, not his own personal thoughts. He thought he was speaking the words of God. I think he thought and believed that God was speaking through him. A person like that is not easy to be around.

That’s not suprising.
So Alda is as pompous in real life as he was in MASH (no surprise there) - this is the first generation of entertainers who don’t care if they alienate most their fan base - Linda Ronstadt said as much in response to the “shut up and sing” fan at one of her old-lady concerts.
