Corrected entry: After Edward kills the boyfriend, it seems that the family is having Thanksgiving dinner. However, the rest of the movie appears to be in the spring time. When then cops come to Edward and Connie's home, they are working in the garden, and bring up the parking ticket she got "4 weeks ago" in SoHo. It just seems that the dinner scene is out of place, since it could not have been fall/winter if they were working in the garden.
Corrected entry: When Connie and Paul make love in the cafe bathroom, we see Connie return from the bathroom like nothing even occurred. However, if she and Paul just got done making love, wouldn't she be all sweaty and out of breath? Even if she wiped her face off, you should still be able to see that she was sweating. Same with Paul.
Corrected entry: When Connie is leaving Paul's apartment to pick up her child she goes to get in her car and you see a parking ticket on the windshield which is dry. In the next shot she gets into the car and the windshield is wet as if it had been raining prior to her entering the car.
Corrected entry: When Richard Gere hits the book dealer in the head there is no way hitting him on top of the head would have killed him because the part of the brain that controls heart, lungs etc is at base of the skull. Even if the brain stem was in top of the skull the snow globe would shatter way before it fractured the skull. It would have had to be almost solid glass.
