Three-time Academy Award® winner Jack Nicholson stars as Melvin Udall, a dysfunctional, crass talking novelist who suffers from obsessive-compulsive disorder. Melvin's daily schedule is thrown into disarray, when the only waitress at his favorite café who's able to stand him, Carol Connelly (Helen Hunt), is absent due to her son's chronic asthma. Driven initially by the compulsion to get back to his daily routine, Melvin offers to help her. But Carol's gratitude leads her deeper into the chaotic life of this misanthropic oddball. When his ailing artist neighbor, Simon (Greg Kinnear) and his tiny dog named Verdell also enter Melvin's life, Melvin, Carol and Simon begin to discover things about themselves, and each other, that they never expected to learn.
