Continuity mistake: Evan arrives at Costco in a polo shirt. He sees the body, then cue music, and you see him driving away in a shirt and tie. (00:09:45)
Suggested correction: I think the shirt and tie scene is a jump forward to Goosman's funeral.
Factual error: In the scene where Evan is talking to Sgt. Bressman in front of Costco, you can see that Bressman is wearing Maryland State Police lapel pins. This is incorrect because the movie is portrayed in Ohio.
Continuity mistake: After Jamarcus cuts his hand, while he's explaining the alien plot, neither of his hands have a cut on them. (01:14:45 - 01:15:45)
