Sour Grapes (1998) is a sharp-edged comedy that explores how sudden wealth can poison even the closest friendships. Directed by Seinfeld co-creator Larry David, the film follows cousins Evan (Steven Weber) and Ritchie (Craig Bierko) whose bond disintegrates when Evan wins a massive $436,000 slot machine jackpot using two quarters borrowed from Ritchie. What begins as a celebratory moment quickly devolves into a bitter dispute over the money's rightful ownership, exposing deep-seated resentments and character flaws.

The film showcases Larry David's signature style of uncomfortable humor and social observation, though it lacks the polished execution of his later television work. Steven Weber delivers a solid performance as the increasingly entitled Evan, while Craig Bierko effectively portrays Ritchie's growing bitterness. The supporting cast, including Karen Sillas and Robyn Peterman, add texture to the escalating conflict.

While Sour Grapes received mixed reviews and holds a modest 5.8 IMDb rating, it offers an interesting early glimpse into David's comedic sensibilities. The film's 91-minute runtime moves briskly through its premise, providing plenty of cringe-worthy moments and moral dilemmas. Viewers should watch Sour Grapes for its examination of friendship, greed, and the absurdity of financial disputes, presented with the awkward humor that would later define Curb Your Enthusiasm. It's a worthwhile viewing for fans of character-driven comedies and Larry David's unique brand of social satire.
