Previously, CBS entertainment president Glenn Geller gave fans an update about The Big Bang Theory season 11, and the actor's contracts renewal. Actors Jim Parsons, Kaley Cuoco, and Johnny Galecki – who play Sheldon, Penny and Leonard in the CBS comedy– contract expire after the 10th season.

Geller told Variety at the Television Critics Association winter press tour, "We are in negotiations, but it is definitely business as usual. We are guardedly optimistic that we will make a deal." When asked if the show could continue without any of the three lead actors, Geller said, "We want to get them all back. That's the goal."
