Tiger may have been the closest thing we've ever seen to a self-portrait of Gene Roddenberry -- totally in love with his wife and kid, yet able to effortlessly attract other women and not hesitating to take advantage of the fact as often as he could, and seeing no conflict there.
Interesting. I didn't know that Gene had gone that far on a regular basis.
As for JoAnna Cameron, I was reading some other stuff last night that suggests that perhaps the 'casting couch' aspect of Hollywood eventually got to her and she left. Maybe that's more speculation though. The other theory I read is that she got typecast. As what? How? Don't know. People fall out of acting for a number of reasons, so who knows what happened.
