Sour Grapes (1998) is a sharp comedy of friendship turned sour over sudden fortune. Directed by Seinfeld co-creator Larry David in his feature film debut, the film follows cousins Evan (Steven Weber) and Ritchie (Craig Bierko) whose Atlantic City weekend takes a dramatic turn when Ritchie uses Evan's two quarters to win a $20,000 jackpot. What begins as a celebratory windfall quickly devolves into a bitter feud over the money's ownership, exposing deep-seated resentments and testing their lifelong bond.

The film showcases Larry David's signature humor—awkward social situations, escalating pettiness, and moral dilemmas played for laughs. Steven Weber and Craig Bierko deliver strong comedic performances, capturing the gradual unraveling of their characters' friendship with perfect timing. The supporting cast, including Karen Sillas and Robyn Peterman, adds to the film's ensemble charm.

While Sour Grapes received mixed reviews upon release and holds a 5.8 IMDb rating, it has gained appreciation as a cult comedy that predates David's later success with Curb Your Enthusiasm. The film's exploration of greed, entitlement, and fractured relationships remains relevant and entertaining. For fans of character-driven comedies and Larry David's unique brand of humor, Sour Grapes offers 91 minutes of witty dialogue and cringe-worthy scenarios that make it worth watching online today.
