Big Bang Theory's Brian Posehn Would Jump At The Chance To Play Bert Kibbler Again

"The Big Bang Theory" might largely focus on the core seven cast members, but the CBS sitcom is chock-full of colorful minor characters, including Bert Kibbler (Brian Posehn). This "gentle giant" of Caltech's geology department is quite the quirky individual who has a passion for his area of study — and Amy Farrah Fowler (Mayim Bialik). Bert only appears in about a dozen episodes, but the actor behind the King of Rock Puns doesn't take his time on the show for granite. In fact, Posehn would jump at the chance to reprise this character.

In an interview with The Cornwall Seeker, when asked if he'd be willing to revisit the role in a reboot, Posehn said, "If it's two years from now, 20 years from now, I had a blast. Not everybody loves sitcoms, and even, in particular, that sitcom. I did. I had a great experience doing 'The Big Bang Theory.' I love that style of comedy. I love a lot of different types of comedy, but the sitcom format is so classic. I feel like it can still be funny. I enjoyed that show. I would do that show or shows like it again."

Today, Posehn is more than willing to bring Bert back to life. However, when the comedian first entered the world of "The Big Bang Theory," he wasn't exactly sure that he'd fit in.

In April 2021, Brian Posehn was a guest star on Mayim Bialik's podcast, "Mayim Bialik's Breakdown." During their nearly 90-minute discussion, the two agreed on how nerve-wracking it was to join an already-established cast. This was especially true for Posehn, whose first appearance doesn't come until Season 6, Episode 18 ("The Contractual Obligation Implementation"), when the socially awkward Bert Kibbler tries to intrude upon the library date of Raj Koothrappali (Kunal Nayyar) and Lucy (Kate Micucci).

"I'd had some shows where not everybody was cool, and everybody was at your show, but it took me a while to come out of my shell," Posehn told Bialik. "That's been a big thing for me my whole life. Do I feel comfortable around people enough to start to make jokes? Because that didn't always fly and some people would go, 'You're dark,' or, 'You're weird.' You hear that enough, you're just like, 'OK, well, I'll just keep that s*** to myself and just get through this.'"

However, once Posehn realized this wasn't the case, he felt more comfortable being himself on set: "It's like, maybe the sixth or eighth episode, I started to go, 'OK, well they don't hate me here.'" Posehn is officially part of the "Big Bang" family, which means, if there's ever a reunion of the original cast, fans can likely look forward to more rock puns.
