Revealing mistake: The teacher has to stop the overzealous Stephanie from signing up to more than one task. Thing is, even before Anna Kendrick grabs the pen from the string, her name is written on the sheet already. (00:03:35)
Revealing mistake: The protagonist broadcasts the description of Emily's car in her vlog. She then receives a mail from a mom in Michigan...or does she? Seems not, because if you look at the window of the mail open in Safari, she is on the Compose tab, not in the Inbox, with a Send message and format and style buttons at the bottom (and she is not replying to the message because the 'from' field is a "michiganmom381" gmail account. (00:39:20)
Revealing mistake: After the report on the Kia, Sean receives a call from the Warfield police department. Sean is a professor in Connecticut, but his mobile carrier as shown in the close-up of the phone is Rogers, a Canadian company. The film was shot in Ontario. (00:39:50)
Revealing mistake: In the sequence with Steph's car spinning out of control once she inadvertently rushes the red light, her son Miles is screaming scared, but the baby actor is laughing. (01:02:50)
Revealing mistake: Stephanie receives a call just after she opened the envelope Nicky gave her, with the brother-f**ker picture. When she picks up the phone, not only it shows the Canadian provider Rogers, but also a time of 4:31 PM, when she just got back home with the kids (who don't do a full time, Sean mentioned 2 PM at the funeral as a time when Emily would drunk-rant at Nicky), plus she still finds Sean busy at work after that despite the city being one hour and a half away. (01:03:10)
Revealing mistake: Stephanie is browsing on the library computer the copy of The Cherry Creek Observer. On the page at the right end of the screen you can see under a title about an assault, a copy-pasted article about autism. (01:20:20)
