When Andrea is in the flower shop helping out, she is not wearing a push-up bra and says she has to go out back to make a call. After she goes outside, she is now wearing a push-up bra.
Even though she never moves her arms, Molly's arm positions as she talks to Isabelle change depending on the camera angle.
The logo on the flower shop van says Country Squire Florist has been serving Louisville since 1973. In the movie, Isabelle was shown to have opened the business sometime after high school. Since she graduated in 1998, it would not be possible for her to have been in business in 1973. This reveals the van used was from an actual Louisville business, complete with correct website and phone number.
Everytime a mobile phone was used the screen was black, so the phones had been off. But they read texts from black screens or have phone conversations.
Andrea knocks out Jasmin by Tasering her through the back pocket of her jeans. A Taser is a less-than-lethal device and does not knock out people. It's effects would also be minimized due to going through 2 layers of denim. Tasers must make contact with skin for maximum effectiveness.
