Sour Grapes (1998) is an underrated comedy that explores how sudden wealth can corrupt even the closest friendships. Directed by Larry David in his feature film debut, the movie follows cousins Evan and Ritchie, whose relationship deteriorates after Evan wins a massive $400,000 jackpot at an Atlantic City casino using two quarters borrowed from Ritchie. What begins as a simple dispute over money escalates into a series of increasingly absurd and humorous conflicts that test their loyalty and character.

The film features solid performances from Steven Weber as the opportunistic Evan and Craig Bierko as the resentful Ritchie, with supporting turns from Karen Sillas and Robyn Peterman adding depth to the ensemble. Larry David's signature cynical humor shines through in the sharp dialogue and situational comedy, though the film maintains a lighter tone than his later work on Seinfeld and Curb Your Enthusiasm.

While Sour Grapes received mixed reviews upon release and holds a modest 5.8 IMDb rating, it has gained appreciation over time as a clever examination of human pettiness and greed. The 91-minute runtime moves briskly through its escalating conflicts, making it an enjoyable watch for fans of character-driven comedies. The film's exploration of how money changes relationships remains relevant, offering both laughs and thoughtful commentary on friendship and ethics. For viewers seeking a smart comedy with Larry David's distinctive voice, Sour Grapes provides an entertaining and insightful experience worth watching online.
