During the Big Bang Theory panel at PaleyFest, Johnny Galecki, Jim Parsons, Kaley Cuoco, and Kunal Nayyar were joined on stage by show producers Chuck Lorre, Steven Molaro, Steve Holland, and Bill Prady. The cast and producers talked about the forthcoming Bill Gates episode and remembering Stephen Hawking, who made a cameo on the show. But one of the biggest reveals of the night was the addition of Jerry O’Connell to the cast as Sheldon’s brother, Georgie whose younger counterpart is played by Montana Jordan in Young Sheldon.

“This is the first time it is being announced, so don’t tell anyone,” said executive producer Holland of the news.

Not much else was said about the future of the show, let alone an end game for the gang. However, they did give some hints about the season 11 finale.  Although it hasnt’ been written yet, it will be a wedding episode for Sheldon and Amy. In addition, there will be bachelor and bachelorette party fun — which is definitely something to look forward to.

A clip of the Gates episode was also shown during the panel and after asking how it was working with him, Galecki was fond of the experience and joked that if he had the chance, to ask a gift from Bill Gates, it would be a plane.

Another notable genius of a guest star to appear on the show was Stephen Hawking, who Cuoco says has been in the foreground of the show for a long time.

Parsons says of working with Hawking: “It was frightening! He is the smartest person you are ever going to meet. It was a true honor.” He also adds, “I always left the room fast before I said something stupid” every time he was in a room with him.

Nayyar said, “I mourned his death like Kunal and like Raj — his presence was a character on our show.”
