The Big Bang Theoryfranchise is now getting another spinoff of the original series, and people are naturally eager to know if the old main cast members will be reprising their roles. TheuntitledBig Bang Theoryspinoffis expected to focus on Stuart (Kevin Sussman), with his girlfriend Denise (Lauren Lapkus) and Caltech scientist Bert (Brian Posehn) also returning. While these three may be the main characters, there is still potential for others to join the regular cast, as well as a wider range ofBig Bang Theorycharacters who could return in Stuart’s spinoff.

SinceThe Big Bang Theory’s ending, the cast members have branched out to other movies and TV roles, proving their versatility as actors after being primarily associated with the same roles for so long. However,they may still choose to return to their once-popular characters in a regular capacity if they miss working onThe Big Bang Theoryor even just make a cameo to please old fans. A few of them have even done this already, suggesting that they in particular are open to working on the new spinoff, even if they have not directly commented on it yet.

Jim Parsons (Sheldon Cooper)

Parsons Is Open To Playing Sheldon Again After Young Sheldon & Some Movies

Sheldon was once one of the three headliners ofThe Big Bang Theory, with the story and comedy being driven primarily by his dynamics with the two others. His return, particularly as a regular character, would be a huge deal whenThe Big Bang Theoryended largely becausehe did not want to renew his contract. However, Parsons recently gave an interview onWho’s Talking To Chris Wallace?during which he expressed openness about returning toThe Big Bang Theory. Parsons possibly teased his return by saying (viaDeadline):

“As we sit here now, no, but I also I would I never say never to anything, because life just changes so much. You know, one of the things is that it was so special as what it was as what it is. And they call it lightning in a bottle for a reason, and you’re able to be certain it wouldn’t be that.”

Parsons kept things ambiguous, but “never say never.” Meanwhile,Parsons has had a continued presence inThe Big Bang Theoryfranchise,even while pursuing movie roles. He serves as a narrator throughoutYoung Sheldonbefore his physical appearance in the finale, offering tidbits about the character’s current life. SinceThe Big Bang Theory, Parsons has worked on movies includingHomeandHidden Figures,but hasn’t seen a major breakthrough as a film actor.

Kaley Cuoco (Penny Hofstadter)

The Flight Attendant Star Says She “Owes A Lot” To Penny & The Big Bang Theory

Also offering a positive update about aBig Bang Theoryreturn is Kaley Cuoco, who played Penny, the actress turned saleswoman who oddly understands Sheldon like no one else for the show’s 12 seasons. AfterThe Big Bang Theory, Cuoco had a short-lived but poignant role in the dark comedy ofThe Flight Attendant, while completing several other projects. Penny is also referenced inYoung Sheldon’s finale, while the entire originalBig Bang Theorycast appears as younger versions of themselves in the spinoff’s season 2 finale.

Leonard and Penny were arguably the best couple on The Big Bang Theory and left fans wanting their relationship on many occasions.

Regarding the new show, Cuoco said (viaPEOPLE): “[…] it really set off my career. I owe a lot to that character, to that show, to [creator] Chuck Lorre. It was some of the best years of my life, and some of the most fun I’ve ever had. I would absolutely reprise that role. 100%.” So fans can probably count on her presence, which may come as a relief when updates about Penny’s life are scarce.At the end ofThe Big Bang Theory,Penny is an expectant mother despite previous reservations about having children,has gone through several big career changes, and might consider moving.

Johnny Galecki (Leonard Hofstadter)

Galecki Has Yet To Comment On A Big Bang Theory Return, Which Is Needed Because Of One Morbid Theory

Completing the mainBig Bang Theorytrio,Sheldon’s former roommate and Penny’s husband has not commented on whether he would return in Stuart’s spinoff.Uniquely, he might have the character who most needs to return, or at least be mentioned, tokill the “Leonard is dead” theorythat arose in the wake ofYoung Sheldon’s finale. While Leonard is a happy father-to-be when he is last seen, Galecki has done little acting since the end of the show. However, he also has a longer career than most of them, going back to being a child star inNational Lampoon’s Christmas Vacation.

Kunal Nayyar (Raj Koothrappali)

Nayyar Is Apathetic About Returning To The Big Bang Theory, Busy With Other Projects

Raj arguably has the most open ending of the mainBig Bang Theorycast, even compared to Stuart,who he often ended up sharing storylines with when they were the two single members of the group. However, while everyone else is in committed relationships with plans for kids or, in Stuart’s case, a thriving business, Raj goes to the Nobel Prize ceremony solo and ends up sitting next to Sarah Michelle Gellar. Despite Raj’s longtime desire to have what most of his friends have, a follow-up on whether he gets this may not be happening.

Let’s look at other memorable Big Bang Theory characters who deserve their own spin-off series.

A few months before Stuart’sBig Bang Theoryspinoff was announced, Kunal Nayyar said with regard to returning as Raj (viaTVLine): “To be honest, it feels a little too soon. Can you do a [revival] only four years after your show ends? That’s not a reunion show; that’s just another season. If [the spinoff] were to happen, we’ll see what the universe says.” Things are still up in the air with Nayyar when his comments are now complicated by the fact that a spinoff is happening. Meanwhile, Nayyar has done an impressive number of under-the-radar projects just in those four years.

Bialik also appears as Amy, alongside a reflective Sheldon, at the end ofYoung Sheldon. While theBlossomactress hasn’t commented on it directly, this suggests her general willingness to hear aboutBig Bang Theorycameo opportunities.
