Although The Big Bang Theory’s series finale aired, the sitcom had cemented its status as one of the all-time great hang-out shows. Alongside Cheers, Friends, How I Met Your Mother, Seinfeld, and New Girl, The Big Bang Theory was a hit sitcom with a massive fan base who mostly tuned in to see how the quirky Pasadena gang handled personal and professional chaos.

Even Stuart Fails to Save the Universe, has been announced, there's no better time to look back on what the cast has said.

Simon Helberg Said The Big Bang Theory Cast Were No Longer In Touch

The Actor Appeared Alongside Melissa Rauch In Night Court Season 3

Jim Parsons Is Not Sure About A Big Bang Theory Comeback As Sheldon

The Series Star Said “I Don't Think So” When Asked In 2024

Reportedly, it was star Jim Parsons’ decision to wrap up his time as Sheldon Cooper that was instrumental in the end of The Big Bang Theory. As such, it might not come as a shock to readers to discover that Jim Parsons wasn’t sure about returning to playing Sheldon when asked in 2024. Speaking to E! Entertainment Online about the possibility of a follow-up show, Parsons said “Look, never say never to anything… Life is long, God willing. But I don't think so.

Parsons’ comments are notable since, unlike his co-stars, he had reprised the role of The Big Bang Theory’s Sheldon after the show ended. Parsons narrated Young Sheldon and, although Young Sheldon’s spinoff Georgie & Mandy’s First Marriage hasn’t featured an appearance from the actor, this does mean he has been in close with the character more recently than his co-stars. Parsons has also earned acclaim for roles in The Boys in the Band and Spoiler Alert since The Big Bang Theory ended.

Kunal Nayyar Thought 2023 Was Too Soon For A Big Bang Theory Reunion

Amy’s Actor Mayim Bialik Wants A Big Bang Theory Reunion

The Blossom Star Said She Would Be “Super Happy” To Play Her Part Again

In Jessica Radloff's 2022 book The Big Bang Theory: The Definitive, Inside Story of the Epic Hit Series, the writer discussed the ways that Parsons’s decision to move on from The Big Bang Theory resulted in mixed feelings among the rest of the cast. This was proven in 2025 when Amy’s actor Mayim Bialik told Yahoo Entertainment that she would be delighted to reprise her role for a reunion.

Star Johnny Galecki also hasn’t commented publicly on the possibility of a follow-up show.

Bialik went on to say that she believed many viewers and creatives who worked on the show would like to see more from the main characters, with “All due respect to Jim.” This comment seems to imply that Parsons could be a major holdout among the main cast when it comes to a possible reunion. However, it is important to note that star Johnny Galecki also hasn’t commented publicly on the possibility of a follow-up show.

A Sequel To The Big Bang Theory Appears Unlikely In 2025

The Cast’s Comments Aren’t Weighted Toward A Reunion

It is not clear whether The Big Bang Theory’s sequel series will ever happen, but it is clear that there is no consensus about the show’s future among its main cast. Parsons’ reticence and Galecki’s silence are counterbalanced by Bialik and Cuoco’s shared enthusiasm, making it tough to guess whether the follow-up show could realistically happen in the near future. It is worth noting that How I Met Your Mother’s reboot, How I Met Your Father, lasted only two seasons.

As such, it might be wise to wait a little longer before rebooting The Big Bang Theory, especially with a spinoff already on the way. If Stuarts Fails to Save the Universe proves a success, this could confirm that there is plentiful fan interest in the show, which might result in a follow-up. However, as of mid-2025, the cast appear to be uncertain about the odds of a sequel series for The Big Bang Theory ever happening.
