Actor Kevin Sussman, best known for his role as Stuart on the long-running sitcom “The Big Bang Theory,” is stepping into a rare leading part in the upcoming spinoff special “Stuart Fails to Save the Universe.” The project, which merges elements of science fiction, fantasy, and comedy, features Sussman’s character navigating through a series of alternate realities in an effort to prevent a multiverse catastrophe.
The special reunites several familiar faces from “The Big Bang Theory,” including Lauren Lapkus as Denise, Brian Posehn as Bert, and John Ross Bowie returning as the physicist Kripke. The production incorporates a variety of extensive special effects, with storylines involving artificial intelligence overlords, wizardry, and even a sequence where the main characters are reincarnated as centaurs.
Sussman, 55, a Staten Island native, has spent much of his career in supporting roles across television and film, including appearances on “Ugly Betty,” “Better Call Saul,” and films like “Wet Hot American Summer.” He began portraying Stuart in a minor capacity in the show’s second season, initially as a guest star, before eventually becoming a series regular by Season 6, though he appeared in only a fraction of the episodes.
Reflecting on the announcement of the spinoff, Sussman described the moment as surreal, recalling how creator Chuck Lorre approached him near the end of the COVID-19 pandemic with the idea of centering a special-effects-driven story on his character. Sussman expressed enthusiasm for revisiting the updated comic book store set, noting it as a particularly exciting aspect of the project.
Despite “The Big Bang Theory” becoming one of television’s most watched series while he remained a relatively peripheral figure, Sussman recalled the contrast between public recognition and his modest personal circumstances at the time, sharing anecdotes about the challenges he faced living in a small apartment and navigating early career uncertainty.
Sussman also spoke candidly about his affinity for nerd culture, recounting his past experience working in comic book stores and brief stints in tech-related jobs during the dot-com boom. He acknowledged that while he does not consider himself a dedicated comic book aficionado, board games remain a particular interest.
Regarding the physical demands of his new role, Sussman mentioned undertaking wire work for the first time, humorously noting a late realization of the fitness required for such stunts, comparing it to the regimen described by Brie Larson for her role in “Captain Marvel.”
Sussman said he frequently receives recognition internationally for his portrayal of Stuart, citing encounters with fans across diverse locations from Chile to the Middle East. He described the experience as a testament to the show’s global reach and expressed pride in being part of a sitcom with enduring cultural significance.
Looking ahead, Sussman expressed interest in exploring different types of roles, including villainous characters and theater work, viewing the spinoff as an opportunity that might open doors to new creative avenues.
