Continuity mistake: In the scene when Gin and Mac are in the elevator, Mac puts in the keycard and presses 86. You then see the position indicator (PI) which shows the floor (70) in an LED, a red up arrow, and the words "EXECUTIVE FLOOR ACCESS GRANTED" in a red box. But when they are trying to escape, after Mac disengages the Door Hold button, you see that the PI has changed. It is all one colour and the floor number is written in a computer font.
