Odeon Leicester Square
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.

Technical specifications
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. Two sets of tabs (curtains) are also installed and used for most performances. The cinema houses all major digital sound systems: SDDS, Dolby Digital and DTS. It had the UK's first wide-screen installed in 1953, and more recently, was the first to have a digital projector installed in 1999. There are 1683 seats ”“ reduced from nearly 2000 to make way for greater leg-room ”“ with a large circle bar and even 'Royal Retiring Room' for visiting monarchs. Seating is divided between the Royal Circle, Rear Circle and Stalls.

The Odeon was built in 1937 to the design of Harry Weedon and Andrew Mather on the site of the Turkish Baths and the adjoining Alhambra Theatre a large music hall dating from the 1850s. The site cost £550,000, the cinema took seven months to build at a cost of £232,755 with 2116 seats. The opening night was Tuesday 2 November 1937, the film shown that night was The Prisoner of Zenda . Until 1967, the interior was a magnificent art-deco auditorium, with a ribbed ceiling, concealing stripped lighting. Two bas relief sculptures of naked nymphs were positioned on the side walls, as if leaping towards the screen. All the seats were covered in a faux-leopard skin material. A rather misguided modernisation in 1967 destroyed most of this grandeur, although since the 1980s, restoration programmes have restored much of the detail, including the figures, seating pattern and much of the ribbed effect on the ceiling. The first wide-screen (screen ratio 1.66:1) ever installed in Great Britain was premiered on the 14th May 1953, the film shown was Tonight We Sing. The British debut of Cinemascope (screen ratio 2.55:1) following soon after on the 19th November 1953 with the quasi-biblical epic, The Robe . The theatre's Chief Engineer, Nigel Wolland, was awarded an MBE for services to the film industry in 2007. The theatre's General Manager, Chris Hilton, was awarded an MBE for services to the film industry in 2010.

Odeon Mezzanine
Tucked next door is the Odeon mezzanine, containing five much smaller screens, each seating between 50 and 60 patrons. The site of this 'mini-plex' was once an alleyway running alongside the main house, until development in 1988 turned it into one of London's first 'mini-plex' cinemas.
