Other mistake: The vlog entry that leads to the finale is #47. Six months pass, the caption say, but in the finale Stephanie is posting her vlog #290. That's more than 40 entries per month, and Stephanie always keeps her entries daily throughout the movie even under the craziest circumstances.
Other mistake: Stephanie's vlog gains over 85,000 subscribers in the space of the minutes it takes for her to livestream from her home to Emily's house. While Youtube has had much larger sudden increases in followers, this is not Youtube, but a private blog that begins from 34,000 subscribers. It seems quite unlikely that even by word of mouth it could have the critical mass to grow by 200% in such a short time, considering that it reached those 30k with a murder story that had media coverage, and it takes then 6 months for her to hit 1 million afterwards, with the amazing scoop and juicy media story that follows. It should also be noted that her figures when she asks to identify the Kia are ridiculously low; she manages to find the same car the police can't find thanks to her channel that has a whopping 1,013 subscribers worldwide at the time.
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)
Continuity mistake: Stephanie and Sean have called the police to file the missing person report. The sergeant to conclude the chat asks him "Not planning any more trips?" In the transition between that shot and the next, the position of his hand changes, putting his pen vertical on the notepad in the second. (00:28:05)
Continuity mistake: At the end of the incest story, Emily says "I can't wait to see you cook", suddenly waiting for Stephanie's answer with her hand wide open instead of with the fingers curled by her chin. (00:22:55)
Continuity mistake: Emily says that she can get a bathtub full of perfume to Stephanie, who got quite drunk. As she starts saying that she's sorry about the pictures, she puts on the table her drink using her right hand, but she had just gestured in front of the camera with an open hand in the shot before. In the same scene, the glass jumps back in her hand when Emily asks her "Wanna trade confessions?" (00:18:55)
Continuity mistake: During the sequence where Emily shows Stephanie how to make a 'real' martini, the lemon on the chopping board is turned differently, appearing also more peeled or less peeled, in the various shots. (00:17:35)
Continuity mistake: When Stephanie gives the beads to the Emily, Emily's martini switches hands multiple times, and even the height she holds the glass at changes between shots. (00:17:00)
Continuity mistake: At the park, Stephanie tells Emily "I think you're a supermom", and Emily tells her "Aww no you don't." She has in the second shot both hands joined in front of the crotch as opposed to the earlier position assumed in most of the scene, with the hands in front of her belly. (00:15:25)
Continuity mistake: When Emily says that "Mother Theresa and I are, like, the same person" her fingers are suddenly wrapped around the glass in the second shot. When Sean arrives and Emily chastises Steph for saying "sorry" again, the glass also switches hands. (00:11:45)
Continuity mistake: Fixing the first martinis, Emily is pouring from the mixer in one shot, and in the reverse angle she's already with both hands doing the finishing touches to the glasses. (00:11:20)
Continuity mistake: When Sean is introduced for the first time, there's an obvious continuity issue with Blake Lively's hair over her right shoulder. (00:12:00)
Continuity mistake: While they are talking about the swear jar, Emily removes the right cuff of her outfit in one shot, but has to fiddle with it for a lengthy period again in the next, since it was back on fully fastened. And then in the next shot she is casting aside...the left, and both are gone. (00:08:00)
Continuity mistake: Asking about the painting, Stephanie turns her head towards Emily. She turns back towards the painting when Emily mentions the East Village, but then in the next shot she is still facing Emily. (00:07:20)
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)
Continuity mistake: Sean goes upstairs after botching Stephanie's name. Emily's glass suddenly reappears in her hand at the cut. (00:13:25)
