Continuity mistake: Elvis' coffee cup sets to his right on the desk in numerous shots. When Elvis has his legs on the right side of the desk, the coffee cup can be seen on the left side. The position of the cup's handle and the amount, if any, of the logo that is visible frequently vary. No one is ever shown touching/moving the coffee cup. (00:20:38 - 00:21:43)
Continuity mistake: The placement and angle of the "Not Friendly" sign on the dead security guard's upper right body changes from when Elvis is looking at him down the hall to when Elvis is kneeling next to his body. Initially, the words are perpendicular to the guard's right leg (angled outward to the right), then to the top of his right shoulder. (00:44:45 - 00:45:19)
Continuity mistake: Hours later when Elvis returned to the dead security guard to take his gun, the "Not Friendly" sign was off the side of the guard's right shoulder, not partially atop the right side of his face and neck like it was earlier. Also, the guard's legs were more parallel instead of the right leg being angled to the right. (00:45:19 - 01:06:35)
Continuity mistake: The camera active times are not quite synchronized. All three do show "10-24 THU", but "CAM 4" shows "03:37:22:?" AFTER "CAM 36" was at "03:38:06:21." Two+ minutes later, "CAM 9" has a slightly earlier time than was shown about 10 seconds earlier on "CAM 9." (01:01:37)
