Why ‘Stuart Fails to Save the Universe’ Will Not Cross Over With ‘Georgie and Mandy’ (Exclusive)

The Big Bang Theory‘s newest spinoff, Stuart Fails to Save the Universe, doesn’t have any rules, but there is one story it won’t explore — a crossover with Georgie & Mandy’s First Marriage.

“[There will be] no East Texas in this show,” creator Chuck Lorre exclusively told Us. “No, I don’t think so. Let them exist in their own worlds.”

Lorre noted that he didn’t see how the two shows could interact. “Lots of stuff gets pitched before we decide what to do,” he added. “So you never know.”

Creator Bill Pardy, meanwhile, suggested a way to make it happen, saying, “We do some time travel.”

Stuart Fails to Save the Universe, which airs Thursdays, follows Stuart Bloom as he is faced with the daunting task of “restoring reality after he breaks a device built by Sheldon and Leonard, accidentally bringing about a multiverse Armageddon,” according to the official synopsis.

Stuart “is aided in this quest by his girlfriend Denise, geologist friend Bert and quantum physicist/all-around pain in the ass Barry Kripke. Along the way, they meet alternate-universe versions of characters we’ve come to know and love from The Big Bang Theory. As the title implies, things don’t go well.”

Stuart (Kevin Sussman) was originally introduced on The Big Bang Theory, which aired on CBS from 2007 to 2019. The show starred Jim Parsons, Kaley Cuoco, Johnny Galecki, Simon Helberg, Kunal Nayyar, Mayim Bialik and Melissa Rauch as a group of best friend scientists and their — sometimes polar opposite — significant others.

The Big Bang Theory spawned a prequel series, Young Sheldon, which focused on Parsons’ original character Sheldon’s life as a child prodigy (Iain Armitage).

Viewers then met Sheldon’s brother, Georgie (Montana Jordan), which paved the way for his love story with Mandy (Emily Osment) to inspire another spinoff, Georgie & Mandy’s First Marriage.

Stuart Fails to Save the Universe, meanwhile, is led by Sussman, Brian Posehn, John Ross Bowie and Lauren Lapkus.

“For me, Stuart came back to me pretty quickly,” Sussman told Us. “Because the original Stuart was sadly not too different than me. So it was pretty much the same.”

He continued: “Stuart has never really been a character where I’ve thought, ‘OK, who is this guy?’ It’s always just been about, ‘What are these circumstances now?’ So less about who I am and more about how do I navigate all this craziness that’s happening?”

New episodes of Stuart Fails to Save the Universe air Thursdays on HBO Max.
