Career(s) of rest of the cast

Yesterday I was watching the episode where Sue breaks up with Darrin and I felt so bad for the buy. I hindsight, knowing that he is basically getting written out of the show and this was his last screen time.

And then it just reminded me that other than Patricia & Neil, which were already popular to begin with, none of the cast members made it big, or even continued acting for that matter. Considering that the show ran for almost ten years, this was not one of those hallmark movie cast that came and went..they were around for a long time. And then just vanished from the screen altogether.

Or have I got it wrong and missed anyone?
