Imagine Stanley Donen’s “Blame it on the Rio” — that ’80s comedy where Michael Caine slept with his best friend’s daughter — taking place instead in New Jersey during the Thanksgiving-Christmas holiday period and you’ve more or less got Julian Farino’s “The Oranges,” a quirk-filled, Sundance-style tale of a pair of dysfunctional families thrown into comic crisis.

Hugh Laurie, in his first big-screen lead since he begun his brilliant run in TV’s “House” seven years ago, plays the bored dad who gets seduced by Leighton Meester, offspring of neighbors Oliver Platt and Allison Janney. Laurie’s wife Catherine Keener flips and moves out, Meester moves in. Everyone is outraged, including Laurie’s children, played by Alia Shawkat (who works at Huffman Koos!) and Adam Brody, as well as the ex-fiancee that Meester rebounded to Laurie from.
