Continuity mistake: Packets of Synchronic were placed on top of the garbage already in the can and were inconsistent from one shot to another. Also, the amount of crumbled papers under the Synchronic decreased. (It is also interesting that no new garbage was placed in the can on top of the Synchronic packets even though over one day had passed).
Continuity mistake: The cigarette the homeless man offered to Frank had a brown filter but was white when Frank had it in his mouth. (00:39:10)
Continuity mistake: The location and intensity of Lavinia's purple hair highlights vary throughout the movie. For example, the purple highlights on the right side were far more pronounced (two wide, distinct, vivid lines) when she got home compared to when she first met Ward. Lavinia rode her horse Comet home, so her hair would have been wind-blown and the highlights would not have been likely to be neatly straight down, especially since she has long curly hair. (00:05:10 - 00:07:13)
Continuity mistake: After Sara's mother sits at the table, the left side of Sara's hair suddenly has two clumps of strands running down her cheek and flipped in front of her chin. Sara's hair changes a few times with different camera angles. (00:44:52)
Continuity mistake: Mulligan hands Gabriel a SIM, and later on it becomes an SD memory card. (01:36:00 - 01:37:27)
Continuity mistake: Sira pours Sprite into a glass until it is about three-fourths full, but the glass is closer to half-full when he hands it to his mother. (00:02:00)
Continuity mistake: During the sign-up for the app at the beginning the girl says "I want to be Sarah." Look at her hair; mostly in front of her left shoulder, just a couple locks on the right side of her face. At the cut, hair behind the left shoulder and a bigger right bang. Camera angles and hairstyles switch again back and forth. (00:02:30)
