Leave the reboots, alternate universes and death/birth/death/birth life cycles to Marvel and DC - the Big Bang Theory wants consistency in its comic book world.
To that end, CBS has upped the role of Stuart, the comic book store owner played by Kevin Sussman, from a recurring one to that of a series regular, per the Hollywood Reporter.
The character becomes the series eighth regular, but the intention is not to have the "lovelorn sad-sack" in each episode. Apparently he will appear in seven to 13 episodes - which is close to the capacity he has been used in previously.
The other core seven characters are Leonard (Johnny Galecki), Sheldon (Jim Parsons), Raj (Kunal Nayyar), Howard (Simon Helberg), Amy (Mayim Bialik), Penny (Kaley Cuoco) and Bernadette (Melissa Rauch). Rauch and Bialik were promoted to regulars, but the other five have been regulars since the beginning.
With the new deal in place, Sussman can be used as often as the writers and show runner needs to use him. Sussman appeared last season on Showtime's Weeds as a recurring character, and had tested the developmental deal waters, but did not move forward with a project.
I'm not a big fan of the show, but it seems to be going steadily with no sign of slowing. How many more seasons do you think they could/should squeeze out of it?
The Big Bang Theory returns Thursday, Sept. 27 at 8 p.m. EST.
