One addendum on the actors' deaths ...
- - Richard Biggs (Stephen Franklin, the doctor for most of the series) was the youngest at age 44.
- - Tim Choate (a favorite recurring character "Zathras")
- - Andreas Katsulas (G'Kar and you may have seen him in TNG a few times), Jeff Conaway (Zach Allen also was in Taxi, Grease), and
- - Michael O'Hare were all in their 60's
There's a lot more than that.
Oh, I know, and you've done an exemplary job with maintaining that list.
I was simply focusing upon the characters/actors bigdaddy
originally mentioned and is likely to become most familiar with soon.
