Continuity mistake: When Ash walks up to the machine we see that, after he puts his card in, the screen is black/off. When he hits the screen there is a split-second clip of the screen looking out at Ash with green text on it. In the next shot the screen is back to black.

Continuity mistake: When Danny and Stacey walk into the Human Resources office, a shot of the woman behind the desk shows the glass countertop has nothing on it. However, when Stacey spins the monitor around, a mouse suddenly appears in the next shot on the glass countertop. (00:30:05)
