Revealing mistake: Addison is driving straight, but cars behind him are shown going around a curve. (Use of a green screen). (00:55:50)
Other mistake: Bo (obviously an adult), who worked with Kevin, was able to walk into the high school cafeteria and take Phoebe into a hallway to talk without any school personnel seeing him or questioning his presence. (00:30:10)
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). (00:18:50 - 00:19:13)
Continuity mistake: Addison put his sweater on (over his neck and arms into the sleeves). After his dad asked him if he was OK, the view of Addison in the mirror showed him putting his sweater on again. (00:16:04)
