The Big Bang Theory” Season 11 is now in production as its stars are now giving their fans a glimpse of their return on the set. In fact, the cast members are happy at being reunited with their co-stars. The likes of Mayim Bialik and Kaley Cuoco are now revealing the television show’s behind-the-scene previews to tease their viewers of the things that are about to come.

Bialik teasing show’s production

Mayim Bialik, who plays the role of Amy Farrah, has been updating her Instagram followers of “The Big Bang Theory” Season 11’s production.

One of the photos the 41-year-old star shared revealed her reunion with her on-screen partner Jim Parsons, who portrays Sheldon Cooper.

As the 44-year-old actor looks upset, Bialik captioned her snap with, “He only looks mad at me.” However, she revealed that he actually missed her, in spite of the look. “I love @therealjimparsons either way,” she said.

In the picture, Bialik and Parsons are together to film an episode of the long-running television show. They are on the set sitting on a couch, but it looks like it is not their iconic sofa. Evidently, the settee looks different and is not the one fans used to know from Sheldon and Leonard Hofstadter’s (Johnny Galecki) Pasadena apartment, People’s Choice reported.

Aside from the reunion photo, Bialik also posted the start of the television sitcom’s production by sharing a selfie while she is holding her script for the coming new installment. The pink folder bears her real and character name, plus the series’ title.

But, she strategically placed her pointing finger over the label to hide the episode’s heading and other details.

Cuoco revealed first episode’s script

This is the same thing Kaley Cuoco, who plays the character of Penny, did when she also shared a shot of her own script for the coming “The Big Bang Theory” Season 11.

The 31-year-old actress used a Rubik cube to hide the first episode’s title. She just captioned it with, “We're baaaaaacccckkkkk!”

Details about the new installment remain scarce and are bound in secrecy. It is already known that Penny already gets wedded to her longtime partner and neighbor Leonard in the series’ ninth season, IBTimes reported. So they already moved out of Sheldon’s apartment and are now living on their own. However, they adopted Raj (Kunal Nayyar) to live with them as his dad stopped giving him financial support to fund himself and his needs.

“The Big Bang Theory” Season 11 will return on Sep. 27 on CBS.
