I had the great good fortune to see Phil Hartman in The Groundlings stage debut of The Pee-wee Herman Show back in the '80s. He played the Popeye-ish Captain Carl, and was absolutely brilliant. His wife Brynn shot him three times in the head on May 28, 1998 while he slept in cartoon Dachsund boxer shorts in their Encino home, then she went and told a friend, then she shot herself in the head. It was later discovered that she was on Zoloft, coke and alcohol. Nuts.
My nephew Jake got me to start watching The Simpsons, and I can't help but feel that twinge of sadness and delight each time Troy McClure appears -- who is featured today on Wikipedia's start page. Hartman's Sinatra was just hilarious, it seems there was no bit that he couldn't put over with his peerless comic timing and panache. He was even able to bring some humor to the tiresome NewsRadio show. His voice had the booming timbre of pure comedy.
His two children were raised by Brynn's family.
