Convention - SDCC 2026: HBO Max Brings Lanterns, Stuart Fails to Save the Universe and House of the Dragon to San Diego

By Mulder, 09 july 2026

HBO Max is once again making a major statement at San Diego Comic-Con 2026, transforming its presence from a traditional promotional campaign into a series of immersive fan experiences designed to place visitors directly inside three of its most anticipated franchises. Rather than relying solely on Hall H presentations, the Warner Bros. Discovery streamer is expanding its footprint throughout downtown San Diego with large-scale activations for the brand-new DC Studios series Lanterns and the highly anticipated comedy Stuart Fails to Save the Universe, while also rewarding House of the Dragon fans with an exclusive advance screening of the sixth episode of the show's third season. The strategy reflects a growing trend among major studios to extend Comic-Con beyond the convention center itself, creating interactive destinations that encourage fans to spend hours exploring fictional worlds instead of simply attending panels. It also highlights HBO Max's confidence in a slate that bridges prestige fantasy, DC mythology and comedy rooted in one of television's most successful sitcom universes.

The first major attraction debuts on July 23 with Stuart Fails to Save the Universe, the latest expansion of The Big Bang Theory franchise and arguably its most ambitious creative leap to date. Instead of returning to the familiar multi-camera sitcom format that defined the original series, creators Chuck Lorre, Zak Penn, and Bill Prady have embraced an adventure-driven, cinematic approach centered on comic book store owner Stuart Bloom, portrayed once again by Kevin Sussman. The premise is delightfully absurd yet perfectly aligned with decades of geek culture references that fueled the original sitcom: after accidentally breaking a reality-altering device created by Sheldon Cooper and Leonard Hofstadter, Stuart unleashes a catastrophic multiverse collapse. Joined by his girlfriend Denise (Lauren Lapkus), geologist Bert (Brian Posehn) and the brilliantly irritating quantum physicist Barry Kripke (John Ross Bowie), Stuart embarks on a desperate mission to repair reality while encountering alternate versions of beloved characters from across The Big Bang Theory universe. The concept represents something that fans have joked about for years—a full-scale science-fiction adventure emerging from television's most famous sitcom about scientists—and even features original theme music composed by Danny Elfman, underlining the production's cinematic ambitions.

To introduce audiences to this unpredictable new universe, HBO Max will recreate Stuart's famous comic book shop, "The Comic Center of Pasadena," inside Sparks Gallery from July 23 through July 26. Rather than functioning as a simple exhibit, the activation has been conceived as a narrative experience in which guests step through an interdimensional portal before traveling across multiple realities connected to the series. Visitors will make character-driven choices that ultimately determine their own superhero archetype, with every path linked to one of the show's central characters. Along the way, attendees will discover elaborate photo opportunities, interact with a replica of the mysterious machine responsible for the multiverse crisis, receive exclusive merchandise and leave with personalized collectibles tailored to their journey. The attraction reflects Warner Bros.' increasing emphasis on experiential storytelling, allowing Comic-Con visitors to experience the show's quirky blend of science fiction, comedy and emotional character work before the series officially premieres on HBO Max later that same day.

The excitement surrounding the new series will continue inside Hall H on July 23, where HBO Max will present an advance screening of the opening episode followed by a panel featuring creators Chuck Lorre, Zak Penn, and Bill Prady, alongside stars Kevin Sussman, Lauren Lapkus, John Ross Bowie, and Brian Posehn, moderated by Felicia Day, herself a longtime icon within gaming and genre fandom. Earlier that afternoon, the cast and creative team will also appear for an autograph session at DC's booth, giving fans an additional opportunity to meet the people responsible for bringing the long-discussed spinoff to life. The decision to stage the series' official launch during Comic-Con underscores Warner Bros. Discovery's belief that the show's strongest audience naturally overlaps with the passionate comic book, gaming and science-fiction communities that have embraced The Big Bang Theory since its debut.

Across town, DC Studios' Lanterns receives an equally ambitious treatment through the "Lanterns Training Headquarters," an elaborate interactive attraction operating from July 23 through July 25 at Venue 808. Inspired by the fictional setting of Rushville, Nebraska, where much of the series unfolds, the activation casts visitors as Green Lantern recruits reporting for evaluation by the legendary Guardians. Rather than presenting static displays, the experience unfolds through a succession of physical and puzzle-based challenges including target practice, trust exercises, maze navigation and escape-room-inspired mysteries taking place inside locations recreated from the show, including a sheriff's office and a neighborhood dive bar. Successful recruits receive their own custom Green Lantern ring before experimenting with a Snapchat-powered interactive mirror that simulates the ring's signature energy constructs, while exclusive merchandise developed by Warner Bros. Discovery Global Consumer Products will also be available. Reservations for the experience open on July 13, emphasizing its limited capacity and positioning it as one of Comic-Con's most sought-after attractions. HBO Max is also extending the promotion beyond the venue itself through surprise giveaways in San Diego's Gaslamp Quarter and dedicated "Lantern Recharge Stations," where visitors can literally recharge both their phones and themselves using decorative Lantern Batteries scattered around the district.

The Hall H presentation for Lanterns on July 24 is expected to become one of Comic-Con's biggest television events. Cast members Kyle Chandler, portraying veteran Green Lantern Hal Jordan, and Aaron Pierre, playing rookie John Stewart, will be joined by Garret Dillahunt, Poorna Jagannathan, and co-creators Chris Mundy, Damon Lindelof, and Tom King for an extensive discussion of the series, accompanied by never-before-seen footage and behind-the-scenes material. Based on DC's iconic Green Lantern mythology, the series follows Jordan and Stewart as intergalactic law enforcement officers investigating a murder in America's heartland, uncovering a mystery with profound cosmic consequences. The project combines the creative pedigree of Chris Mundy, known for acclaimed crime dramas, with the storytelling experience of Damon Lindelof and celebrated comic writer Tom King, while executive producers James Gunn and Peter Safran continue building the interconnected DC Universe on television. The first two episodes are directed by James Hawes, with Stephen Williams, Geeta Vasant Patel, and Alik Sakharov directing subsequent installments, further illustrating the premium production values surrounding one of HBO Max's flagship genre series debuting on August 16.

Fantasy fans have not been forgotten either. On the evening of July 25, HBO Max will present an advance screening of Episode 6 from the third season of House of the Dragon inside Room 6DE at the San Diego Convention Center. The screening will be introduced by co-creator and showrunner Ryan Condal, offering audiences an opportunity to experience the latest chapter of the Targaryen civil war before its official release. Adapted from George R. R. Martin's Fire & Blood, the series continues exploring the bloody Dance of the Dragons nearly two centuries before the events of Game of Thrones. Season three features returning performances from Matt Smith, Emma D'Arcy, Olivia Cooke, Steve Toussaint, Rhys Ifans, Fabien Frankel, Ewan Mitchell, Tom Glynn-Carney, Sonoya Mizuno, Harry Collett, Bethany Antonia, Phoebe Campbell, Phia Saban, Jefferson Hall, Matthew Needham, James Norton, Tom Bennett, Kieran Bew, Kurt Egyiawan, Freddie Fox, Clinton Liberty, Gayle Rankin, and Abubakar Salim, with executive producers including Ryan Condal, George R. R. Martin, Sara Hess, Melissa Bernstein, Kevin de la Noy, Vince Gerardis, David Hancock, and Philippa Goslett.

Taken together, HBO Max's Comic-Con 2026 strategy illustrates how major studios increasingly view the convention as a citywide celebration rather than simply a series of convention-center presentations. By combining immersive attractions, exclusive screenings, talent appearances and hands-on storytelling, the platform is giving fans multiple ways to engage with its biggest upcoming productions while reinforcing the distinct identities of each franchise. Whether stepping into the collapsing multiverse of Stuart Bloom, training to earn a Green Lantern ring alongside Hal Jordan and John Stewart, or witnessing the latest chapter of the Targaryen civil war before anyone else, attendees will find HBO Max offering one of the convention's broadest and most ambitious entertainment lineups, further cementing San Diego Comic-Con as the premier launchpad for genre television.
