Based on the Broadway play by Neil Simon, this tells the story of two mismatched friends, Felix Unger and Oscar Madison. Felix is a neat, tidy, and healthy nut, a photographer at a portrait studio, and a connoisseur of classical music. Because of this, his wife divorced Felix and threw him out of his apartment for good. Desperately in the need of a place to live, he moves in with his longtime childhood friend, Oscar Madison, a sports journalist for the New York Times. What he realizes is that Oscar is the exact opposite of him: sloppy, messy, and doesn't eat the right foods. Felix's cleaning, hygienic tips, and healthiness annoys Oscar while Oscar's crazy world of living like a pig upsets Felix. But in the process they'll learn that love, trust, and friendship are more important than living in different worlds.
