Fresh off the Knicks’ first NBA title in 53 years, longtime superfan Ben Stiller will direct a multi-part documentary series tracing the franchise’s history, culture and championship return.

Ben Stiller is turning the New York Knicks’ championship season into an HBO event.

The actor, filmmaker and longtime Knicks superfan has confirmed that he is directing a multi-part documentary series about the team in partnership with A24, HBO and the NBA. The project will explore the history, culture and legacy of the Knicks, culminating in the franchise’s first NBA championship in 53 years. Stiller announced the project shortly after the Knicks defeated the San Antonio Spurs to win their first title since 1973, a moment that instantly became one of the defining New York sports stories of the century.

Stiller confirmed the news on X, writing that he “couldn’t be more excited” to make the documentary with A24 and HBO about the Knicks. He also discussed the project on Jalen Brunson and Josh Hart’s ‘Roommates’ podcast, telling the championship-winning players that the series will cover all eras of the franchise rather than focusing only on the title run. Stiller said he has already been filming some material himself on his phone and expects production to continue over the next year, including additional shooting during next season.

That access could make the project especially valuable. According to A24, the series will trace the full arc of the Knicks from the 1990s through the improbable, record-breaking run that finally returned a championship to New York. The company also described the project as featuring unprecedented NBA access, never-before-seen footage and a definitive look at one of basketball’s most iconic stories.

The timing could not be stronger. The Knicks’ 2026 championship ended a drought that had stretched across generations of fans, from the legacy of Walt “Clyde” Frazier and the 1973 title team to the Patrick Ewing era, the heartbreak of 1999 and the long, often painful rebuilds that followed. By the time Brunson, Karl-Anthony Towns and the current roster brought the Larry O’Brien Trophy back to New York, the victory was about more than basketball. It became a citywide release.

Stiller was one of the most visible celebrity fans throughout the Finals, frequently appearing courtside and filming pieces of the team’s run on his phone. He traveled to San Antonio for Game 5 alongside other Knicks supporters and franchise icons, including Spike Lee, Timothée Chalamet, Tracy Morgan, John Turturro, Frazier and Ewing. People reported that the documentary will cover the team’s full history and include behind-the-scenes footage along with extensive player and team access.

The series also fits naturally within A24 and HBO’s recent nonfiction strategy. Both companies have leaned into high-profile documentary projects that combine cultural specificity with broader audience appeal, and the Knicks offer one of the richest subjects in sports: a team with an enormous fan base, decades of mythology, celebrity visibility, Madison Square Garden history and a championship ending that would have sounded almost too clean if it had been scripted.

For Stiller, the project is also personal. His Knicks fandom has long been part of his public identity, and this championship run placed him in the middle of a cultural moment that stretched from the arena to the streets of New York. The documentary gives him a chance to capture not just what the Knicks won, but why the win mattered so deeply to a city that had waited since the early 1970s to see it happen again.

That broader emotional context may be the key to the series. The Knicks are not simply another NBA franchise with a title story. They are a team whose failures, near-misses, celebrity courtside culture and Madison Square Garden aura have made them central to New York’s sports identity even when the on-court product was difficult to defend. A proper documentary can treat the championship as the ending of one story, but also the payoff to decades of loyalty, frustration and civic obsession.

POPULAR ON THE CINEMA GROUP

The involvement of the NBA should also give the series access to archival material and game footage that could help connect the franchise’s eras more cleanly. From the championship teams of the 1970s to the bruising 1990s, the 1999 Finals run, the years of dysfunction and the eventual rise of the Brunson-led team, the Knicks have more than enough history to sustain a multi-part format.

The championship has already become a major entertainment story beyond sports. Chalamet’s viral “way rather this than the Oscars” celebration, Spike Lee’s emotional presence, Mariska Hargitay’s Finals enthusiasm and the star-packed Knicks parade all reinforced how much the team’s victory belonged to New York culture as well as the NBA. Stiller’s documentary now has the opportunity to turn that moment into a lasting record.

No official title, episode count or premiere date has been announced yet. But with Stiller directing, A24 and HBO producing alongside the NBA, and production expected to continue into the next year, the Knicks’ long-awaited title run is already getting the prestige documentary treatment.

For a franchise that spent 53 years waiting for another championship, the cameras arrived just in time.
