'The Big Bang Theory' season 10 spoilers: Cast returns to work on upcoming season of hit CBS show


Filming for season 10 of “The Big Bang Theory” started last week, and it appears that series stars Kaley Cuoco (Penny), Johnny Galecki (Leonard), Jim Parsons (Sheldon), Mayim Bialik (Amy), Kunal Nayyar (Raj), Simon Helberg (Howard) and Melissa Rauch (Bernadette) are having the time of their lives as they posed for a group photo while taking a break from filming the new season.

Cuoco took to her Instagram account on Aug. 17 to post the picture, which shows the gang standing on the set of the comedy series. The photo was captioned, “#season 10 woot woot! @thebigbangtheory we back babyyyyy.” The actress also posted a Polaroid shot of the group which shows them with their hands out as they celebrate their 10th season.

Season 10 is expected to pick up right where the series left off, after Sheldon’s mother, Mary (Laurie Metcalf), and Leonard’s father, Alfred (Judd Hirsch) left Penny and Leonard’s wedding to spend some time together at their hotel. While Sheldon and Leonard were horrified at the prospect of becoming brothers, Penny was delighted about it, and it remains to be seen if what exactly happened between the two will be revealed when the show returns.

Meanwhile, Howard and Raj got an email from the U.S. Air Force about their newly-finished guidance system, and all throughout the finale, Howard was convinced that the government was watching them. The new season is expected to continue this storyline, along with Bernadette’s pregnancy and the next stage of Amy and Sheldon’s relationship.

There are rumors that the show will take its final bow after the season 10 finale, but CBS Entertainment president Glenn Geller told reporters at the Television Critics Association summer press tour that everyone involved wants to have more seasons of the show.

“We are very confident that everyone involved wants more ‘Big Bang’ past year 10,” said Geller (via Entertainment Weekly). “I know Warner Bros. will make those deals.” Though he declined to give details about a season 11 renewal, Geller said that they will keep airing the show as long as fans want to watch it.

“I hope it lasts forever,” he added.

“The Big Bang Theory” season 10 premieres on Sept. 19 at 8 p.m. ET on CBS.
