Uncle Buck

Uncle Buck is a 1989 American comedy film directed by John Hughes and starring John Candy and Amy Madigan, with Jean Louisa Kelly, Gaby Hoffmann, Macaulay Culkin, Jay Underwood, and Laurie Metcalf in supporting roles.

Bob suggests asking his brother, Buck Candy, to come watch the children, to which Cindy objects. While they are upper middleclass suburbanites, Buck is unemployed, lives in a small apartment in the city, enjoys drinking and smoking, and earns his living by betting on rigged horse races. He drives an old and crackling 1977 Mercury Marquis every time he turns off the engine, it makes a loud backfire. His girlfriend, Chanice Madigan, owns a car repair business. They have been together for eight years and she wants him to get a job so they can get married and have a family. Buck accepts a job at Chanices garage, but is unenthusiastic as he enjoys his freedom. Since no one else is available to help Bob and Cindy, they have no choice but to turn to Buck, who agrees to help. He informs Chanice that he will need to start work later as he tells of the family emergency. Given that Buck has earned an antiwork reputation, Chanice thinks Buck is trying, as usual, to bluff his way out of working.Buck quickly befriends Miles and Maizy, but the rebellious Tia is standoffish, and the two engage in a battle of wills. When Buck meets Tias obnoxious boyfriend, Bug Underwood, he warns her that he is only interested in her for sex. Buck repeatedly thwarts her plans to sneak away on dates with Bug. Over the next several days, he deals with a number of situations in comedic fashion, including taking the kids to his favorite bowling alley, making enormous pancakes for Miles birthday, ejecting a drunken birthday clown from the property, speaking with the school assistant principal about Maizy, and handling the laundry when the washing machine wont work. ........
