Chuck Lorre has started off the podcast confessions with a bang.

“The Big Bang Theory” co-creator, 72, revealed a regret of his when it came to Kaley Cuoco’s character, Penny, on the series, which ran from 2007 to 2019 on CBS.

“We had so many episodes to go before we started to understand that there was a brilliance to Penny’s character that we had not explored,” Lorre said while on the first-ever episode of “The Official Big Bang Theory Podcast” on Monday.
