5 Young Sheldon Actors Who Played Different Characters On The Big Bang Theory

As an actor who’s had the unique opportunity to bring two distinct characters to life within the same TV universe, I can truly appreciate the richness and depth that Lance Barber has brought to both “The Big Bang Theory” and “Young Sheldon.”


As a big fan of “The Big Bang Theory” for over a decade, I was bummed out when the show ended after season 12 in 2019. But luckily, “Young Sheldon” stepped up to fill the void left by my beloved sitcom. This spin-off series takes us back in time and focuses on Sheldon Cooper’s early years growing up with his family in Texas. Iain Armitage does an amazing job portraying young Sheldon, and Jim Parsons adds continuity between the two shows through voiceovers. Just like “The Big Bang Theory,” “Young Sheldon” has welcomed some impressive guest stars throughout its seven seasons, including Ming-Na Wen, Ray Liotta, and Elon Musk. But that’s not all! Several actors from “The Big Bang Theory” have also made appearances on this prequel sitcom.

Chuck Lorre, famous for his repeated collaborations with actors across different projects, is illustrated by the cases of Jamie Pressly and Brooke D’Orsay. Pressly graced two of Lorre’s successful sitcoms, “Two and a Half Men” and “Mom,” while D’Orsay, who portrayed distinct characters on “Two and a Half Men,” now plays Christy in “The Big Bang Theory.” Notably, “The Big Bang Theory” and “Young Sheldon” share the same universe, although set in different time frames. Lorre and co-creator Steven Molaro unhesitatingly invite these actors back to contribute, often in delightful ways. Here’s a peek into five such actors who have graced both shows.

Melissa Tang

Melissa Tang, who stars in “The Kominsky Method,” didn’t have major roles in “The Big Bang Theory” or “Young Sheldon,” but her appearances were far from insignificant. In “The Big Bang Theory,” she made her first appearance in the second episode of Season 9 as an ex-girlfriend of Leonard’s (Johnny Galecki) who had come back to work at Caltech. Her return caused tension between newlyweds Leonard and Penny, but it turned out that Penny’s jealousy was unfounded. Mandy Chow, Tang’s character, had no memory of her past romance with Leonard. Initially causing a rift, Mandy’s return eventually helped strengthen Leonard and Penny’s relationship as they recognized the importance of commitment and choosing to be together, even during challenging times.

Tang was among the initial actors to make guest appearances in both shows, marking her debut on “Young Sheldon” in its pilot episode. On “The Big Bang Theory,” her character, named Ms. Fenley and a music teacher at Medford High, contributed to the show’s themes, as she previously did by interacting with other key characters. In “Young Sheldon,” an 11-year-old Sheldon, feeling excluded in high school, finds solace in the music room and impresses Ms. Fenley with his piano prowess. This encounter sets the stage for Sheldon’s genius in the series, demonstrating that he has various potential career paths but is already committed to science.

Octavia Spencer

Octavia Spencer adds charm and intrigue to the second season of “The Big Bang Theory” with her guest role in Episode 5. In this scene, the “Hidden Figures” actress appears at the DMV counter, engaging in a challenging interaction with Sheldon. When none of his friends are available to drive him to work, Sheldon decides to apply for his learner’s permit. With an abundance of queries, he turns to Spencer’s character who, after growing tired of his incessant questioning, eventually approves his application to put an end to it. Although her part on the show is limited, Spencer’s appearance introduces a captivating storyline, allowing viewers to witness an unconventional side of Sheldon – a genius with a glaring incapability: the art of driving.

In simpler terms, Spencer’s significant presence as an authoritative figure in “The Big Bang Theory” did not go unnoticed by the producers. Consequently, they invited her back for Season 7 of “Young Sheldon,” where she portrayed Rhonda Thomason, Connie Tucker’s probation officer. Although this was a minor role within the “Big Bang Theory” franchise, Spencer jumped at the chance as she is an avid fan of “Young Sheldon.” Her enthusiasm was amplified by working alongside Lance Barber, who shared with TV Insider that they took a photo together before he even had the opportunity to ask for one. How thrilling that was for her!

Michael Trucco

Penny stands out among the love interests on “The Big Bang Theory” for having the greatest number, including noteworthy ones such as Kurt (Brian Patrick Wade), Zack (Brian Thomas Smith), and her future husband Leonard. It’s worth mentioning Michael Trucco’s character, Dr. David “Dave” Underhill, who makes an appearance in Season 2, Episode 11. Penny is introduced to Dave by Leonard while they are collaborating on a project at Caltech. Initially, Dave seems like the ideal match to end Penny’s string of unsuccessful relationships. However, it turns out that he has been deceiving her and is already married.

Penny discovers, through experience, that her feelings towards Dave are more about the concept rather than the reality, much like Mary (Zoe Perry) in “Young Sheldon,” who develops an attraction to the fictional character Rusty (Michael Trucco) in one of her novels. In the sixth season’s third episode, Mary finds solace in romance novels while still distanced from her church. Inspired, she decides to write her own story and creates both Rusty and her alternate persona, Marie. However, she learns a valuable lesson about the limitations of fantasy. Interestingly, this plotline featuring Trucco served not only to link “Young Sheldon” to its prequel but also to reveal some intriguing parallels between Mary and Penny’s experiences.

Jason Kravits

Jason Kravits is an actor who graced both “The Big Bang Theory” and its prequel “Young Sheldon.” Unlike other actors on this list, Kravits made an appearance on “Young Sheldon” before joining the original sitcom. In the sixth episode of Season 1, Kravits portrays Dr. Hodges, a NASA administrator who speaks to Sheldon and Georgie’s high school class. Determined to show off his intellect, Sheldon suggests an innovative way for NASA to fly reusable rocket boosters, which could save significant taxpayer funds. However, when Dr. Hodges disregards him, Sheldon becomes determined to prove him wrong and discovers his deep-rooted passion for theoretical physics – a career that “The Big Bang Theory” fans would later recognize.

After appearing on “Young Sheldon,” Kravitz re-entered the “Big Bang Theory” world several years later with an entirely new character. The producers were evidently pleased with his portrayal of Dr. Hodges, leading them to invite him back for a role that created conflict between Penny (Rauch) and Bernadette in Season 12’s Episode 17. Kravitz’s character, named Danny Jacobs, is a pharmaceutical salesman who attempts to persuade Penny to join his team during a conference in San Diego when they cross paths. Despite the allure of his financially enticing proposition, Penny eventually declines.

In simple terms, Kravitz’s guest roles on “The Big Bang Theory” had significant impacts. The bond between Penny and Bernadette was strengthened through their challenges, while Sheldon might not have achieved his Nobel Prize without the career advancements that resulted from these appearances.

Lance Barber

Lance Barber stood out among other guest stars on “The Big Bang Theory” and “Young Sheldon” by securing a regular role in the latter as George Cooper, Sheldon’s father. He made his debut in Season 5, Episode 11 of “The Big Bang Theory,” portraying Leonard’s high school bully Jimmy Speckerman. The group encounters Jimmy unexpectedly at a bar where Leonard is surprised by his former tormentor acting friendly. With lingering resentment from their past, Leonard arranges to meet Jimmy for a drink in an attempt to assert himself. However, their conversation under the influence of alcohol results in a false apology that Jimmy forgets the next day.

It’s intriguing how the portrayal of this character differs from Sheldon’s description of George Cooper Sr. on “The Big Bang Theory” compared to how he is depicted on “Young Sheldon.” This discrepancy arises because Barber was given the chance to add depth and humanity to the character during its creation. Jimmy, the previous role Barber played, served as a valuable stepping stone for him, leading him to secure the part of George. As Barber shared in an interview with HCTV, “Chuck Lorre [the show’s creator] values those he connects with. … Being part of his shows is a remarkable opportunity.”

Barber found great fulfillment in portraying George, going beyond just being the comic relief as he did on “The Big Bang Theory.” His depiction of George significantly influenced Sheldon’s character, as evidenced by the emotional eulogies for Iain Armitage and Jim Parsons’ characters in the “Young Sheldon” funeral episode.
