Steve Finch (
Matthew Broderick) is a nice-guy optometrist, living in the picturesque town of Cloverdale, Mass., with his loving wife Kelly (
Kristin Davis), rebellious teen daughter Madison (Alia Shawkat), and 10-year-old son, Carter (Dylan Blue). Steve's known as "The Christmas Guy". He loves the holiday and goes all out every year -- decorating, caroling, tree-trimming, and organizing the annual family photo (with matching sweaters, of course). Everything is peachy-keen in Steve's neat, organized world, complete with a wall calendar to keep things on track. Then Buddy Hall (
Danny DeVito) moves into the house across the street with his lovely wife Tia (Kristin Chenoweth) and shapely daughters Ashley and Emily (real-life twins Sabrina and Kelly Aldridge of
8th and Ocean). Buddy's a likeable guy, but he feels invisible, which makes him want to put up a mammoth Christmas display bright enough to see from outer space. It's his chance to be somebody. So up go thousands of lights, giant Santas, snowmen, synchronized music, and even live animals -- including a donkey, camel, cow, and sheep. It's all too much for Steve, who feels threatened and fights back, enlisting help from his son to thwart Buddy's efforts.
