Deck the Halls (2006)

Revealing mistake: You can see Buddy and Finch's stunt doubles in the ice skating scene. And when they are showing a close up of them you can tell that they are not really ice skating, but just doing the ice skating movement.

Continuity mistake: When Steve Finch crosses the street to talk to Buddy Hall outside the hardware store, he raises his collar around his neck. Slightly further on in the scene, when the two are in front of the tree, he places his hands in his pockets. The two then walk back to Hall's pickup, at which point Finch's collar is down, and returns to being up when they finish walking. At no time does Finch remove his hands from his pockets.

Plot hole: Buddy discovers a website, myearth.sat. The site, like Google Earth, contains satellite images of every square inch of the planet. Buddy can see his neighbor's house but not his own house. He decides to cover his house with lights so it can be "seen from space." There is absolutely no reason why the site would show every house in the world except Buddy's, except that the oversight is required in order to advance the plot.

Tia Hall: Honey, the girls are having a great time showing everybody the lights. I pray to God that's the only thing they're showing.
