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)
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.
Revealing mistake: In the evil woman's dramatic scene after she kills the children, her knife flops around like it is made of rubber, but sounds solid when she throws it in the sink. (01:22:35)
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. The sun is shining on the backs of the Muslims heads indicating that they are facing west even though Mecca would be off to a much more easterly direction from Brooklyn.
Factual error: When Esposito revisits the murder scene, he asks Morales whether he would prefer the culprit to receive the death penalty. Morales answers that he would not, claiming that to doze off and fall asleep (hinting at execution by lethal injection) would be too good for the man who raped and brutally murdered his wife. Execution by injection has never been practiced in Argentina - where the last execution was carried out in 1916, by shooting - and was legally enacted only in 1977 and practiced the first time in 1982 (in both cases by the state of Texas). Thus, it seems anachronistic that anyone would equate the method with capital punishment in 1974, when the scene is set. (00:24:00)
