Nicky Katt, the versatile character actor best remembered for his roles in Dazed and Confused, Boiler Room, and Boston Public, has died at the age of 54. His attorney, John Sloss—founder and partner of Sloss Law—confirmed the news, though no cause of death has been disclosed.
Early Start in Acting
Born on May 11, 1970, in South Dakota, Katt began his acting career as a child. He made his television debut in a 1980 episode of Fantasy Island, followed by numerous appearances on popular shows throughout the 1980s. His early credits include CHiPs, Father Murphy, Code Red, Herbie, the Love Bug, Voyagers!, Quincy, M.E., V, The Facts of Life, Dear John, and Uncle Buck.
He transitioned to film with roles in Underground Aces (1981), Gremlins, The ‘Burbs, Martians Go Home, and Sister Act, gradually building a reputation for his strong supporting performances.
Breakout Role in Dazed and Confused
Katt’s breakthrough came in Richard Linklater’s 1993 cult classic Dazed and Confused, where he played Clint Bruno, a hot-headed high schooler with a love for fighting, his car, and getting high. His character’s memorable brawl with Adam Goldberg’s Mike Newhouse remains one of the film’s standout scenes.
Katt continued his collaboration with Linklater, appearing in subUrbia (1996), Waking Life (2001), and School of Rock (2003), further cementing his place in indie film circles.
Acclaimed Roles in Film
In 2000, Katt starred in Boiler Room as Greg Weinstein, a smooth-talking stockbroker alongside Giovanni Ribisi, Vin Diesel, and Ben Affleck. The film became one of his most recognized performances.
He frequently worked with acclaimed director Steven Soderbergh. In The Limey (1999), Katt played a hitman. In Full Frontal (2002), he portrayed an egotistical actor cast as Adolf Hitler in a bizarre stage play titled The Sound and the Fuhrer. Soderbergh praised Katt’s performance, calling it “absolutely fearless” and noting his unique approach to portraying an abstraction of Hitler with dry, ironic humor. The duo reunited once more in 2013 for Behind the Candelabra.
Katt’s other film credits include notable appearances in Sin City, The Way of the Gun, A Time to Kill, Death Proof, Snow Angels, The Sitter, Batman & Robin, and Christopher Nolan’s Insomnia (2002) and The Dark Knight (2008), in which he played a member of the S.W.A.T. team.

Memorable Television Work
On the small screen, Katt earned acclaim for his role in Boston Public (2000–2002) as Harry Senate, a passionate and unorthodox high school geology teacher. The character often clashed with the educational system but remained devoted to helping students, making him one of the show’s most talked-about characters.
His TV résumé also includes guest appearances on Friends, Monk, Love & War, Law & Order, The Guardian, King of the Hill, and ER. His final on-screen performance was in an episode of the Hulu series Casual, according to IMDb.
A Complex Performer with a Cult Following
In interviews, Katt often spoke candidly about the struggles of the acting profession. In a 2002 conversation with the Los Angeles Times, he reflected on the “low-level malevolence” of Los Angeles and the desperation that hangs over the industry. He revealed how he channeled those frustrations into his characters, particularly in Full Frontal, which offered him the chance to explore the absurdity of performance and celebrity.
