Goofs

At about halfway into the movie, when Maureen gets to Kyra's home, she goes to the refrigerator to get some water. You can clearly see the outline of her bra through her T-shirt. However, when she goes into the closet and removes the shirt, there is no brassiere.

A little past the halfway mark, Maureen is browsing photos on her laptop of Kyra wearing different clothes at various events. You can see and hear her click on the photos. While all laptops have a track pad and some have extra mechanisms to provide the mouse actions, Maureen is using a MacBook, which only has a track pad, thus there should be no clicking sound.

When Maureen is texting, her texts are frequently answered immediately, usually in less than one second. There is no time lag built in for the other person to read her text and type in their response. This goof is probably intentional. Building in a time lag for the other person to read/respond to her messages would considerably slow down the pacing of the movie, so responses to her texts were probably prepared in advance and sent immediately.

About 17 minutes into the film, Maureen (Kristen Stewart) receives a Skype call from Gary on her laptop. When she accepts the call, you can very clearly see that she's actually starting a video and not accepting a real Skype call.

When Maureen is seeing the video on the Swedish artist, the Swedish speaker is obviously not a native speaker as some pronunciation is quite strange.

In the Cartier shopping scene, a hair is visible in the upper right hand corner of most of the interior close-ups.

When Maureen was texting with 'Unknown', her texts are usually immediately seen and replied to. On her phone, it shows the time of when the text was read. However, some of the times shown are not logical. There was a scene where her last text was read at 17:46 when she was still on the train. Then she sent a text, got on a scooter, and finally sent another text after she got to Kyra's home from the train station. But the 2 messages were seen in the same minute (17:57). Right after that, she traded a few texts with 'Unknown' and it seems to have happened in a few minutes but the last text she sent in that scene was read at 19:01, more than 1 hour later from when she got home.
