Knicks superfan Ben Stiller has finally confirmed that he is making a documentary about the New York basketball team that recently won the NBA championship. “Couldn’t be more excited to make this doc with A24 and HBO about the NY KNICKS!!!!!!” he wrote on social media with the obvious hashtag, #LETSGOKNICKS. Stiller, like Spike Lee and other celebrities, was a fixture at the team’s NBA Finals games in recent weeks, filming the games on his iPhone.
The filmmaker added on the Roommates Show podcast, hosted by Knicks players Jalen Brunson and Josh Hart, that he was making the doc with the NBA’s and Madison Square Garden’s cooperation. Stiller told the players that the crux of the film wouldn’t be just their stunning 2026 victory but also “all eras of the Knicks,” according to ESPN.
“You know, there’s so many great eras,” he said. “And this team, I think, you know, when you look at the Seventies championships, the Nineties runs and then this team doing it again, I think there’s just so much within that.”
Ostensibly, that means Stiller’s multipart docuseries would cover 80 years’ worth of Knickerbockers history, though he explicitly said the show would “trace the full arc of the franchise from the Nineties to the improbable, record-breaking run that finally returned a championship to New York.”
Stiller began working on the doc “a little bit before the playoff run,” he said and he expects it to stretch on over the year ahead, into the next season.
“If you’re lucky enough to have that access and have that point of view, I feel like it’s great to be able to share that,” Stiller told The New York Times of his penchant for posting his iPhone clips. “I think that’s the biggest part of it, is to be able to share that point of view because I feel so grateful to have that. And then it’s fun to be just witnessing it.”
The 2026 Finals, where the Knicks faced off with the San Antonio Spurs, became one of the most closely watched sporting events in the team’s history. They won four out of five games, earning their first NBA Championship since 1973. Celebrities and notable public figures who attended the games, in addition to Stiller and Lee, included President Donald Trump, Taylor Swift, Timothée Chalamet, Tina Fey, and Tracy Morgan; Knicks fans booed the president. A championship parade for the team is scheduled to take place in lower Manhattan on Thursday.
As a director, Stiller is best known for movies like Reality Bites, The Cable Guy, Zoolander, Tropic Thunder, and the TV series Escape at Dannemora and Severance (not to mention his own Nineties gem, The Ben Stiller Show). In 2025, he directed a documentary about his parents, Jerry Stiller and Anne Meara, titled Stiller & Meara: Nothing Is Lost.
