Continuity mistake: When Chris drives up to Edgar's house, his windshield is dirty but suddenly clean thereafter. (00:11:37 - 00:12:57)
Continuity mistake: Some of Aunt Jillian's bangs (parted down the middle) were separated from the left side, partially covering her eye when she went into Chris and Nicole's house but the gap was gone when the camera shifted, and she was walking toward them. Aunt Jillian had "The Goonies" in one hand and a bag of Dunkin' Donuts in the other, so didn't move her hair forward to close the gap. (00:17:23)
Revealing mistake: Jon is part of Shane's pack/tribe, but his face/image is visible in his rear view mirror when it should not have been. (00:57:00)
Other mistake: Jon's vehicle does not have the front license plate that is required in California. (00:57:23)
