Big Bang Theory showrunner Steve Molaro says the series could end after Season 10.
While the comedy series has already been renewed for three more years by CBS, Molaro told THR that the 10th season could be the last in the show’s run:
I’m going to move forward along with [co-creator/EP] Chuck [Lorre] that 10 is the end unless we’re told otherwise. These are decisions that are so far away I can’t really even think about that. I have no choice but to move forward … it’s so far away (laughs). The mindset is it’s going to be the 10 and then we’ll see what happens after that.
Molaro adds that he would OK with the show ending with 10 seasons, as long as it gets a proper ending:
I would be OK, yes, as long as we do it right. My concern is that we do it right and we end this show in a way that is as befitting of these characters that we respect and love. As long as we can have the opportunity to end it in a way that serves them all properly, that’s my concern — more than the number of seasons.
