Revealing mistake: Addison is driving straight, but cars behind him are shown going around a curve. (Use of a green screen). (00:55:50)
Continuity mistake: At the school's memorial service for Kevin, Addison was seated in the upper right-hand corner of the auditorium, a few seats from the wall. A view of students in the large mid-section shows them looking toward the upper left-hand corner while he is talking. (Their heads are turned in the wrong direction to be watching him).
