Here's a comprehensive summary of the "Uncut Gems" Wikipedia article:
"Uncut Gems" is a 2019 American crime thriller directed by Josh and Benny Safdie, starring Adam Sandler as Howard Ratner, a charismatic but reckless Jewish-American jeweler and gambling addict in New York City's Diamond District. Howard desperately seeks to pay off mounting debts, including $100,000 to his loan shark brother-in-law Arno, by retrieving and selling a rare 600-carat black opal he imported. His high-stakes schemes involve lending the precious gem to basketball star Kevin Garnett for a playoff game, only to pawn Garnett's NBA championship ring to fund a colossal bet. These escalating gambles and confrontations, including being ambushed by Arno's enforcers and a disastrous attempt to rig the opal's auction, plunge him into relentless peril. Premiering on August 30, 2019, the film earned widespread critical acclaim and box office success, with Sandler's intense, against-type performance frequently hailed as the best of his career, and notably marked the Safdie brothers' final collaboration before their partnership dissolved in 2024.
