For twelve seasons, television’s most famous comic book store had an unforgettable owner. With his awkward charm, dry wit, and endless love of geek culture, Stuart Bloom became one of the most beloved characters in The Big Bang Theory. The actor behind him is Kevin Sussman, one of the most recognizable faces in television comedy.

While millions of fans know him as Stuart, Sussman’s career began long before The Big Bang Theory. Early on, he appeared in productions such as Ugly Betty, where he played Walter, as well as films including Sweet Home Alabama, Hitch, Made of Honor, the Coen Brothers’ Burn After Reading, and Ang Lee’s Taking Woodstock.

His career also includes appearances in acclaimed television series such as Weeds and Better Call Saul, showcasing his versatility across both comedy and drama.

Beyond acting, Kevin Sussman has built a successful career as a writer. Over the years, he has sold original projects to major studios and networks including Sony, FOX, CBS, and Amazon Studios, expanding his creative work beyond the screen.

In 2026, he returns to the world of The Big Bang Theory as the lead of Stuart Fails to Save the Universe, the brand-new spin-off centered on Stuart Bloom. The single-camera multiverse comedy features appearances from members of the original cast, who return in cameo roles portraying alternate versions of their characters as villains.

At San Diego Comic-Con Málaga 2026, you’ll have the opportunity to meet one of television’s most beloved comedy actors and the performer who turned Stuart Bloom into one of the most memorable characters in modern sitcom history.
