Sadly, I believe we are down to 1 living director, 2 living writers and zero living composers for TOS.
114 actors (with speaking roles) alive out of 401. Youngest actor with speaking part is 64. Amazingly, only 3 TOS actors died so far this year!! That's crazy since the average age must be early 80s for the surviving actors.
Well, older actors arguably abuse less of the hard-stuff substances, which reflects on their comparative longevity.
Which director's still kicking, Grant?
