Continuity: During the party scene, a woman wearing a green dress can be seen lying dead on the floor, a few scenes later we can see her alive and running out of the house with the crowd.
Continuity: Early in the movie a phone booth is shown with the Pacific Bell logo. After Alexandra wishes to be back in her apartment, the phone rings and a camera shot of the phone shows a Bell South logo.
Crew or equipment visible: In the scene when the camera has a wide shot of the park/play house you can see the camera crane's shadow in the bottom right corner.
Continuity: Towards the end of the Beaumont party scene, Alex and the security guys are in the hallway with the killer statues. One of the security men falls to the floor and his earpiece falls off. Throughout the scene, it keeps changing position from being on the floor next to him, to back on his ear, to being on his ear in a different position.
Continuity: When the Djinn traps the guard inside the glass door, the man is facing the Djinn, and is trapped in the door still facing that direction. But when the Djinn opens the door to walk in the shop, the guard inside the door is now facing the other direction, toward the inside of the shop.
Continuity: When Josh and Alex sit down after their tennis match, Josh's tennis racket vanishes from his hands between shots.
Factual errors: Security is trying to help Alex escape. Each security guard is using a semi-automatic pistol, and when the clips are empty, the gun is heard to be making a double click sound. No semi-automatic pistol will make a double clicking noise when the slide is drawn back, as these are shown to be, when the clip is empty.
Continuity: After the explosion in the laboratory, Josh is laying on the floor, injured. His face is covered in blood, however during the scene the amount of blood on his face keeps changing. In close ups of his face his lips are free of blood, but in wider shots his lips are covered in thick amounts of blood.
Continuity: When the tramp presses himself up against the drug store window, the positions of him arms change from up or down between shots.
