Ben Stiller Is Making a New York Knicks Documentary for HBO and A24

Ben Stiller has officially confirmed what Knicks fans suspected for months: he’s been documenting the team’s historic championship run, and now it’s becoming a major documentary series.

The actor, director, and die-hard Knicks fan announced he’s partnering with A24, HBO, the NBA, and Madison Square Garden on a multi-part documentary about the franchise. The project will chronicle not just the team’s recent title win, but explore multiple eras of Knicks history.

Stiller revealed the news during an appearance on The Roommates Show, hosted by Knicks stars Jalen Brunson and Josh Hart, expressing his enthusiasm about bringing the franchise’s story to the screen. His excitement is justified—he’s been courtside at MSG for years, but during the 2026 Finals, he became nearly as visible as the players themselves, constantly recording on his phone.

“I’ve been collecting footage throughout the playoff run,” Stiller shared, later taking to social media to announce the partnership with the two premium outlets.

What many didn’t realize is that production actually began before the Knicks embarked on their championship-winning postseason. Filming is expected to continue into next season, with additional interviews and behind-the-scenes material planned to provide deeper insight into the organization and its players.

The series currently has no official title, episode count, or release date. But with A24 and HBO involved—and Stiller’s genuine passion for the franchise—expectations are already sky-high for what could become the definitive portrait of the Knicks’ long-awaited return to glory.
