Stiller was a frequent courtside attendee at Madison Square Garden during Brunson and the Knicks' run to the 2026 NBA title.

He has since announced plans to create a Knicks documentary through A24 and HBO featuring footage from his own iPhone camera.

Shelton made it to Friday's semifinal by upsetting reigning U.S. Open champion Carlos Alcaraz, while Tiafoe dropped two sets before coming back to win his quarterfinal in five against Alex Michelsen.
