The license plates of the Mitsubishi car the FBI agent drives change from 221-HPK before they enter the house to 460-SER when they exit.
Near the end when Rebecca Scott shoots Miles Archer in the chest, she shoots him just below his left chest pocket. Yet in the next shot it shows .the bullet hole in his chest just above his right pocket.
In the hotel scene, when Rebecca is awakened by the sound of her cell phone, an Iphone, it clearly shows that she needs to slide to open the phone to be able to answer the phone, when she puts it to her ear and says ''hello'', we see that she hasn't pressed ''slide'' thus she never answered the phone.
In the opening sequence, the shadow of the helicopter filming the shot is clearly visible over the beach and houses until it fades out into the next shot.
Near the end of the film, in a scuffle between Agent Nelson (Cuba Gooding Jr.) and Inspector Hendricks (Evert McQueen), Agent Nelson is supposed to be in handcuffs, but while falling to the couch, it can be seen that Agent Nelson's hands are without 'cuffs. The next scene of the scuffle, however, shows Agent Nelson in handcuffs again.
Agent Nelson is wearing a wedding ring and then makes a pass towards Rebecca by putting his hand on her butt at the end.
