Actor and filmmaker Ben Stiller is documenting the New York Knicks' experience in the 2026 [1] NBA Finals using his iPhone.

Stiller is a longtime superfan of the team, and his decision to film the series highlights the emotional intensity surrounding the Knicks' unexpected performance this year. His involvement blends the worlds of professional sports and independent filmmaking, capturing the high-stakes atmosphere of a championship run in real time.

Stiller has been positioned courtside at Madison Square Garden in New York City to record the events [2]. He said the current finals feel different for the team, reflecting his deep emotional investment in their success [3].

The filming process has coincided with the volatility of the series. After the Knicks suffered a loss in Game 3 [4], which ended the team's winning streak, Stiller reacted with visible emotion [5]. Reports on his reaction vary, with some noting he vowed to stop wearing a finals shirt after the first loss, while others said he joked about taking extreme action following the Game 3 [4] defeat.

There are conflicting reports regarding the final destination of the footage. Some sources said Stiller is filming the documentary on his iPhone [1], while other reports suggest he is allegedly filming the project for HBO [6].

Regardless of the platform, Stiller continues to use his courtside access to capture the historic nature of the moment [2]. The footage aims to document the specific tension, and hope, associated with the Knicks' push for a title in 2026 [1].
