Re: G\'Kar a semi-regular?
The differences between cast member, recurring character, guest star, special guest star, etc. are all kind of skewed sometimes anyway.
Tracy Scoggins was considered a main cast member of Crusade, but she was in only 2 (maybe 3) out of the 13 produced episodes. Robert Rusler was in the opening credits during the whole 2nd season of B5, but his Lt. Keffer was an extremely minor character and in only 6 episodes. Jeff Conaway was in 7 2nd season episodes but wasn't a full cast member until the 3rd season (and even then he was in only 9 3rd season episodes).
With the exception of one addition in the 4th season and one change in the 7th season, Deep Space Nine's regular cast remained relatively unchanged, but many recurring characters in the 7th season probably appeared just as often, if not more so, than Cirroc Lofton did as Jake Sisko.
Amber Benson appears in almost every episode of Buffy The Vamipre Slayer, but still isn't in the opening credits as a regular cast member.
I'm assuming Heather Locklear was a major player in Melrose Place, but I think she was always listed as a Special Guest Star and yet that title still appeared in the opening introduction.
The nurse characters on ER are always in the guest star list even though many of them appear in almost every episode. The doctor characters Malucci and Jing-Mei left the hospital at about the same time. The guy who played Malucci is no longer in the credits, but the actress Ming-na is. So, does that mean Jing-Mei is coming back to County General, or could a contract dictate that the actress continue to appear in the opening credits for the rest of the season?
So, is there any exact science to how actors are credited? Is there a minimum on-camera time they have to have to be considered cast members or to be in the weekly opening credits? Maybe Joe would know the answer to that (I'm glad he's around more often lately).
