I was sitting around bored so I decided to compile a list of actors and actresses who have starred, co-starred or had a recurring role in more than one show at different times during their career. This is what I have so far and I will be adding to it as I think of more. Please feel free to add your own! :D

Gregory Sierra was never on Chico & The Man (surprisingly, since he appeared in almost every other show in the '70s, heh). He was the lead in the short-lived A.E.S. Hudson Street, a semi-regular in the final season of Soap, and played the late Greg Giraldo's father in the brief Common Law.
