A movie theater is a building or venue for viewing movies. Most cater to the general public. The general public can attend by buying a ticket. Most movie theaters are equipped for digital cinema projection.
Some if not all theaters offer 2D film which has been around a long time, 3D film, or Imax. 3-D film makes it so that the viewer sees the picture in three dimensional. Those who view the movie in 3D usually borrow special glasses to wear while they are watching the show. Depending on what the system is, these glasses are usually polarized. The number of screens in theaters that are 3D are increasing today. In many theaters, the price of the ticket for 3D showings is more expensive but people don’t usually mind it because they are going for the 3D experience. As for Imax, it is a system using film with a bigger frame size than the 35 mm film. the theaters use an over-sized screen and special projectors to show their films.
As for the design of the theater, it usually consists of a single auditorium with many rows of seats, as well as an area containing a box office so that you can buy tickets, a counter for buying drinks and snacks, and a bathroom. Stadium seating is popular in modern multiplexes. Stadium seating gives those who are viewing the movie a clear line of sight over peoples heads who are sitting in front of them. Depending on how the angle is of the chairs, the aisle may have steps.
Beside multiplexes, there are other theaters where you can enjoy a movie in your car. This is called a drive-in movie theater. The drive in theater is an outdoor parking area with a movie screen at one end and a booth that projects the movie at the other end. Those going to the movie drive into the parking space to watch the movie. Sometimes the sparking spaces are sloped upwards so that the person watching the movie can see better. The sound of the movie is either broadcast on an FM radio frequency or on a portable loudspeaker that is located by each parking space. Because they are outdoors, the drive-in theater is usually only operated seasonally.
So as you can see, the movie theater is a place where people can gather together to watch movies and have a good time.
