Revealing mistake: Will answers a video call from Sandra, and after he says what's up, her video appears, and she's already talking mid-sentence. (00:02:45)
Revealing mistake: The Georgetown University surveillance feed shows every camera using the same IP address (126.113.203.60). The exact same IP is seen earlier on feeds for Washington DC street corners, the Pentagon, and NSA HQ. In reality, these would all have different addresses. The movie just reused the same overlay without changing the details. (00:02:20)
Revealing mistake: In the Dulles Airport surveillance feed scene, the system is supposed to be doing facial recognition on everyone, but the two people walking toward the camera have their faces blurred out. This was probably done for filming privacy, but in reality it makes no sense for the system to censor itself. Will would be looking at non-blurred faces. This indicates it was taken from real footage recorded earlier and then edited for the movie. Signs and clothing logos are also blurred in this "live security footage." (00:01:50)
Revealing mistake: Both NSA and Pentagon feeds display "HD" and "4K" at the same time, which are different resolutions and wouldn't be listed together. The NSA feed also shows a battery icon despite being a fixed security camera, not a portable device. These are unrealistic HUD elements for professional surveillance systems. It is also the same display with battery at 80% from both cameras, indicating it is just a copy-paste in the editing. Several other shots have the exact same overlay later as well. (00:01:30)
Revealing mistake: When Will launches "Guardian," the window shows the Restore icon (two overlapping squares) in the title bar even though the app isn't maximized (desktop is visible around it). In Windows, that icon only appears when a window is maximized; a non-maximized window should show a single Maximize square. (00:00:45)
