At Dunlop Plaza, when Jack and Walsh leave the stairwell and head into the hallway, the camera follows close behind Walsh as they turn the corner. As it follows them, you can plainly see the torso of a man in a blue shirt with his arms crossed to the left of the screen along with someone's forearm. This happens just as Walsh exits the stairwell, holding out his gun in the opposite direction and before the camera whips around to Walsh and Jack. The gun blocks the face of the blue shirt man, and only the forearm of another can briefly be seen.

The clock on screen reads 01:44 when Keith and Nicole Palmer show up. Then, at the next scene with Teri and Alan, it reads 01:42. Since this isn't Time Bandits, the editor has assumed the latter was intended to read 01:45 and adjusted it accordingly.
