Yeah I must admit, I didn't quite get the intention of this thread. People seem to be just listing second and third tier characters, but none that I would consider a "guest star". I believe people like Lois Chiles and John Beck got "also starring" credit; is that the criteria here, anyone not in the main cast?
I definitely agree about Mark Grayson. He very well could have been in the opening credits.
