Early Life and the UCB Foundation

Brett Gelman was born and raised in Highland Park, Illinois. His journey into the arts began with classical training at the University of North Carolina School of the Arts. However, it was his move to New York City that defined his comedic voice. Gelman became a staple of the Upright Citizens Brigade (UCB) Theatre, where he developed a reputation for high-energy, absurdist, and often confrontational characters.

Before his mainstream success, Gelman was a favorite in the "Alt-Comedy" scene, appearing in numerous Adult Swim specials and cult-favorite podcasts. His ability to blend intense drama with biting sarcasm allowed him to transition seamlessly into television and film.

The Career Turn: From Fleabag to Stranger Things



Gelman’s career reached new heights through two iconic, yet vastly different, television roles:

  • Fleabag (2016–2019): Gelman played Martin, the alcoholic and antagonistic brother-in-law. His performance was so convincingly loathsome that it earned him international acclaim and established him as a master of the "love-to-hate" character.
  • Stranger Things (2017–2026): As Murray Bauman, the former journalist turned conspiracy theorist, Gelman became a fan favorite. His character’s evolution from a paranoid recluse to a karate-kicking hero alongside Joyce Byers and Jim Hopper is one of the show's most celebrated arcs.

In addition to these hits, Gelman has starred in films like Lemon (which he also co-wrote), The Disaster Artist, and Lyle, Lyle, Crocodile. In 2024, he released his first book, The Terrifying Realm of the Possible, a collection of short stories that showcases his talent as a writer.

Latest Projects: 2025 and 2026 Updates

As of early 2026, Brett Gelman continues to expand his creative footprint. He recently starred in the Apple TV+ series Lady in the Lake and headlined the dark comedy series Entitled. He is also set to appear in the highly anticipated upcoming films Children of Blood and Bone and André Is an Idiot. Fans also saw him return for the epic conclusion of Stranger Things, where Murray played a pivotal role in the final battle for Hawkins.

Personal Life and Advocacy

Brett Gelman’s personal life has seen significant happy milestones. After his divorce from filmmaker Janicza Bravo in 2018, Gelman found love with actress and singer Ari Dayan. The couple announced their engagement in 2023 and celebrated their wedding in a beautiful, artistic ceremony attended by many of their Hollywood peers.

Off-screen, Gelman is an outspoken advocate for social justice and is known for being a vocal supporter of the Jewish community and Israel. He often uses his social media platforms to address antisemitism and promote cultural dialogue, balancing his public persona as a comedian with serious activism.

Legacy of the "Anti-Hero"

Brett Gelman’s legacy is built on his refusal to play it safe. He is one of the few actors who can make an audience feel incredibly uncomfortable one moment and erupt in laughter the next. By embracing the weird, the dark, and the conspiratorial, Gelman has secured his place as an evergreen icon of modern character acting.
