Continuity mistake: Monica's station wagon and the moving van Jacob drove to their new property in Arkansas are not parked in the same positions moments after their arrival. Initially, both vehicles are at some distance from the mobile home (or trailer) and are roughly parallel.

Continuity mistake: The kids are in the car with their dad, and despite the best efforts from the youngest, they are reached by his teacher. As the dad starts the "You were killing us" joke, his hand is on/off the steering wheel between shots more than once. (00:07:15)
Continuity mistake: Early in the film when Jake gets in his car to head off to pick up his son, his seatbelt is on although there is no sight of him putting it on, then, as he pulls away the seatbelt is off.
Continuity mistake: The protagonist receives her gift from Molly Shannon. She unwraps it and puts the discarded wrapping on the counter. When we see it again at the end of the scene, the wrapping is much less torn apart than the first time around (or at least has been arranged neatly). (00:09:45)
Continuity mistake: James lit the cigarette he gave Amanda, and she was shown taking one puff. Amanda tells part of the Empty Man story and the ashes on the tip of her cigarette are the same when she takes a second puff.
