The Odeon Leicester Square is a cinema which occupies the centre of the eastern side of Leicester Square, London, dominating the square with its huge black polished granite facade and 120 feet (37 m) high tower displaying its name. Blue neon outlines the exterior of the building at night. It was built to be the flagship of Oscar Deutsch's Odeon Cinema Circuit and still holds that position today. It hosts numerous European and World film premieres including the annual Royal Film Performance.
The Odeon is the largest single-screen cinema in the United Kingdom and one of the few with its circle and stalls remaining intact. The cinema is fully equipped to show films in 35mm, 70mm and digital on a large screen, as well as extensive stage facilities for the occasional live show. The cinema still has an operating Compton organ, its console lit from within by coloured lighting, and a safety curtain detailed in 1930s art-deco motifs.
