Sure we know of Jack Black and Phil Hartman in Atari commercials.
It was not long ago I noticed it was Jane Krakowski in THIS commercial for Solar Fox. She has had quite a Stage / Television / Movie career. https://en.wikipedia.../Jane_Krakowski
Heh always thought she was a cutie. Sadly, she IS going the Hollywood way in that she is afraid to grow old gracefully (she is 47 now) but I remember her from way back in this 2600 commercial.
