Factual error: The part of the movie where they have had the morning updates at the police station, Richard Gere later walks on the sidewalk and stares deliberately at a pair of Muslims praying.

Continuity mistake: Catherine goes home after sex with Chloe yet she later receives a picture on her phone from Chloe in which she's asleep afterwards. When did she fall asleep?
Suggested correction: There's no indication that she went straight home. Lots of people doze off after sex.
Continuity mistake: During the fight in the bathroom, Zoe and the villain break a bathroom stall door and side-wall down. In the next shot the door is back up in its original position. It is the same door that is beside the urinal, not another stall, as it's a small bathroom with only one stall and urinal. (00:28:30 - 00:30:00)
Continuity mistake: After seeing the aborted baby, Quaid goes into the bathroom and plunges his head into water. His hair, however, is perfectly dried afterward. (00:35:35)
Visible crew/equipment: When Chun-Li and her family arrive at their new home at Hong Kong, as the old servant opens the door, the reflection of the boom mic is visible on the black door. (00:01:55)
