A projection screen is an installation consisting of a surface and a support structure used for displaying a projected image for the view of an audience. Projection screens may be permanently installed on a wall, as in a movie theater, mounted to or placed in a ceiling using a rollable projection surface that retracts into a casing, painted on a wall, or portable with tripod or floor rising models as in a conference room or other non-dedicated viewing space. Another popular type of portable screens are inflatable screens for outdoor movie screening.

A movie theater, cinema, or cinema hall, also known as a movie house, picture house, picture theater or simply theater, is a business that contains auditoria for viewing films for public entertainment. Most are commercial operations catering to the general public, who attend by purchasing tickets.
