Other mistake: Garry and Wyatt are sitting on the side of a 'planter box prop' that was built for the movie, not a bench, when Ian and Max spill the Icee (slush) on them. (00:32:52)
Suggested correction: This isn't a mistake. Regardless of the fact it might have been built for the film, malls regularly have planter boxes that people can sit on (I've done it myself). Nothing in the film suggests they were sitting on a bench.
Other mistake: In the mall scene, when Gary and Wyatt sit down on the bench and Max and Ian dump the Icee on them, notice how much slush is actually dumped on them from a 32 oz. cup. (00:32:55)
Other mistake: When Chet is getting on everyone's case about everything that is wrong with the house, he says to Lisa, "I didn't think it was a whale's d__k, honey" in reference to the missile going through the house. The French subtitles has "bitte" to mean the portion of the male anatomy. The correct French word is "bite". "Bitte" means either "bite" or "bollard" in English. (01:14:10 - 01:16:10)
