The Odeon Leicester Square, which dominates the east side of the square, hosts many film premieres.
It has a capacity for 1,683 people, arranged in circle and stalls.
The last 70mm film showing was Armageddon in 1998, after which the theatre began to use digital technology.
The projection room still contains some of the original 1930s decor and normally houses two projectors.
The Empire opened in 1962.
It was previously the largest cinema on the square, but in 2013 it was subdivided to cater for an IMAX screen.
The Odeon West End, on the south side, opened in 1930.
It was not generally used for premieres and was earmarked for demolition in 2014, to be replaced by a ten-storey hotel including a two-screen cinema.
Westminster City Council reported 400 new jobs would be available after the redevelopment.
Vue West End, on the north side, near the north east corner, was the first cinema in Europe to show a 3D film with Chicken Little in 2006.

A short distance from the west of the Square, on the south side of Panton Street, is the Odeon Panton Street.
The Prince Charles Cinema, to the north of the square opened in 1962 with a "satellite dish" design where the audience looks upwards to the stage.
The cinema became known for showing pornographic and erotic films during the 1970s, including Emmanuelle (1974).
It later became a favourite venue for showing cult films, including The Rocky Horror Picture Show (1975) and a sing-along version of The Sound of Music (1965), and marathon performances including all seven Muppet films back to back.
Prices are considerably cheaper than the main cinemas in the square; in 2013 a ticket for a new release at the Prince Charles cost £10, compared to £24 at the Odeon.
