Other mistake: On the first day of the Big Bounce, during the dancing, a white towel-like object is dropped on the floor and in the next shot it is gone.
Other mistake: When Paul is making the DVD, there's a record of Terri performing a song she wrote(One more mile to Jericho). At the very end, outside the school the kids start play some music together with Terri singing. That's supposed to be some random thing like it was before, but actually they play and sing Terri's own song. How come?
Other mistake: When Jordan Cahill sings on the porch of the old house, he is holding the guitar but he is not actually playing it (he's not really fingering on the fingerboard).
Other mistake: Near the beginning of the movie when Lola and her family are in the car driving to New Jersey, the car gear shift lever is in park.
Other mistake: At the beginning, Pierre's doorbell rings. He goes to answer it, only to see Pépinot walking up the driveway. How could he ring the doorbell while walking up the driveway?
