The Great Outdoors (1989)

It's vacation time for outdoorsy Chicago man Chet Ripley (John Candy), along with his wife, Connie (Stephanie Faracy), and their two kids, Buck (Chris Young) and Ben (Ian Giatti). But a serene weekend of fishing at a Wisconsin lakeside cabin gets crashed by Connie's obnoxious brother-in-law, Roman Craig (Dan Aykroyd), his wife, Kate (Annette Bening), and the couple's two daughters. As the excursion wears on, the Ripleys find themselves at odds with the stuffy Craig family.
