‘Stuart Fails to Save the Universe’ Episode 5 Release Date and Time
Fans of the ‘Big Bang Theory’ spinoff have a new date circled on their calendars. Episode 5 of ‘Stuart Fails to Save the Universe‘ is set to arrive on August 20, 2026. That puts the show right on track with the weekly rollout it has followed since its debut, and it means Stuart Bloom’s disastrous multiversal road trip is only getting started.
The series premiered on Thursday, July 23, on HBO Max, with new episodes dropping every Thursday leading up to the season finale on September 24. The core premise has stayed consistent since the first episode, with the show following a hapless comic shop owner who accidentally breaks reality itself, and each new week seems to dig the character into a deeper hole.
The ‘Big Bang Theory’ Spinoff Release Schedule
A new episode drops every Thursday at 6 PM PT, which is 9 PM ET, and that pattern continues until September 24, 2026. After episode 5 on August 20, the schedule rolls straight into episode 6 on August 27, episode 7 on September 3, episode 8 on September 10, episode 9 on September 17, and the finale on September 24.
The full first season runs 10 episodes, with each one clocking in around 30 minutes, and the show is currently airing on HBO Max in the United States. That runtime keeps things brisk, which fits a series built around jumping between wildly different alternate realities every week.
The series has already delivered its fourth episode, which released on August 13, 2026. With episode 5 close behind, the show is maintaining a steady clip that should carry it comfortably to its already scheduled finale.
As for what comes after season 1, HBO Max has not yet officially renewed ‘Stuart Fails to Save the Universe’ for a second season, with any decision likely hinging on audience response once the season wraps.
Stuart Bloom’s Multiverse Armageddon Plot
The story picks up years after the finale of ‘The Big Bang Theory,’ with Stuart still running his comic book store and dating his girlfriend Denise, until he accidentally damages a device left behind by Sheldon and Leonard. That malfunction rips open the fabric of reality itself and sends Stuart tumbling into alternate universes he never asked to visit.
Stuart is joined on this mission by Denise, his geologist friend Bert, and physicist Barry Kripke, and together the group has to bounce between different versions of the world they know while trying to prevent total multiversal collapse. Along the way they run into alternate takes on familiar ‘Big Bang Theory’ faces, and true to the show’s title, nothing about their fix-it plan seems to go smoothly.
Each episode is built around a brand new reality, which gives the writers room to spoof everything from sci-fi blockbusters to post-apocalyptic dramas and classic comic book tropes. That structure is part of what has made the season feel unpredictable, since viewers genuinely don’t know what genre Stuart will stumble into next.
According to co-creator Bill Prady, the show intentionally starts off balance, telling TVLine that the story begins in the wrong universe with instructions for how to set things right, and that fixing the timeline is the entire mission driving the season.
HBO Max Streaming Details and Cast
Kevin Sussman is back in the lead role as Stuart Bloom, joined by Lauren Lapkus as Denise, Brian Posehn as Bert Kibbler, and John Ross Bowie reprising his role as Barry Kripke. Bowie’s return was confirmed back in February 2025, alongside a talent holding deal with Warner Bros. Television, while Ryan Cartwright, Josh Brener, and Tommy Walker joined later that year as recurring guest stars.
The series was officially titled in March 2025, and HBO Max handed it a full series order that July, with filming running from September 2025 through February 2026. That gave the production plenty of runway to build out the various alternate-universe sets the show relies on week to week.
‘Stuart Fails to Save the Universe’ is currently streaming exclusively on HBO Max, with subscription plans starting at 10.99 dollars with ads and 18.49 dollars for the ad-free tier. That places the spinoff behind the same paywall as its predecessor and the rest of the ‘Big Bang Theory’ extended universe.
Despite the multiverse-hopping premise, star Kevin Sussman has been clear that this isn’t just a rehash of the original sitcom. He has said fans shouldn’t expect more of the same, positioning the spinoff as a genuinely different kind of show built around action and science fiction elements rather than the couch-bound comedy of the flagship series.
Bill Prady and Chuck Lorre on the Show’s Vision
Series co-creator Chuck Lorre described the show back in February 2026 as a science fiction action adventure comedy, and said he wanted a project that pushed him into unfamiliar territory, especially on the visual effects and computer graphics side, since most of his career has revolved around two people talking on a couch. That’s a notable shift for a producer best known for traditional multi-camera sitcoms.
The show’s central hook, watching Stuart, Denise, Bert, and Kripke stumble through one broken reality after another, gives the writers room to lean into bigger set pieces than the original series ever attempted. It’s a gamble, but one that seems designed to justify the jump to HBO Max’s bigger production budget.
With episode 5 arriving August 20 and the finale locked for September 24, the season is now more than halfway through its run, and the stakes for Stuart’s universe-saving mission only look messier from here. What alternate reality do you think Stuart and the gang stumble into next, and does the multiverse have any chance of surviving Kripke’s involvement?
