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 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)
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)
Plot hole: *SPOILER* Near the end of the movie, Elvis said, "And, of course, we warned LA and Pasadena's PD in advance [of what they would be doing on-air]." In light of the public's outrage over the 10/30/1938 "War of the Worlds" radio broadcast (reporting an apparently believable but fabricated Martian/alien invasion) plus the sheer number of emergency calls that listeners could be expected to make during the course of Elvis' live radio broadcast, police would not be likely to "go along with" his plan. (01:30:06)
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)
Revealing mistake: Obvious use of a "green screen" when Elvis and Dylan are sitting on the steps in the stairwell. The five distinct steps that could be seen behind them become a gray wall and the blue handrail posts to the right of the screen become oddly grouped, appearing to be parallel to the right side of Elvis' shoulder/back. (01:09:00 - 01:09:25)
