The end credits do not call any of the people trapped in the elevator by their names, just their occupations or what they are, e.g. "Older Woman."

9 minutes into the film, as the elevator door closes, the last Passenger puts his arm in the way to stop it, but it is not visible in the mirror. This reveals that, to avoid revealing the camera in the mirror, they superimposed video into the scene.
