Bonnie Hunt played the character Sarah, who freed him from the game.
Yes. Pam dawber and Robin Williams were very good friends. He stuck up for her many times. They wanted her to wear a badded bra and she refused and Robin backed her up. He also made sure that there were episodes written where she could show off her comedic talents and shine.

Robin Williams was a drug addict. He admittedly suffered from addiction problems most of his adult life. He also suffered from bipolar disorder, and he had said that at one point when he made a movie or a show, he would stop taking his meds and snort cocaine to regain his functionality.
Sadly, Robin Williams committed suicide in August 2014.
The judge denied him joint custody of his children, and his ex-wife wanted to hire a nanny. He didn't trust strangers to take care of his children. He also believed that no one could love them more than he did.
