BFI IMAX was designed by Bryan Avery of Avery Associates Architects[3] and completed in May 1999. The screen is the largest in Britain (20m high and 26m wide). It has a seating capacity of 500 and a 14,000 Watt digital surround sound system. Although the site is surrounded by traffic and has an underground line just four metres below, the architects and engineers accounted for this in their design and the entire upper structure sits on anti vibration bearings to prevent noise propagation.[4]
In 2012, the screen was replaced and a digital IMAX projector was installed alongside the existing 70mm projector. In July 2012, the BFI announced that Odeon Cinemas had been selected to operate it for the next five years, with the option of termination after three years. Odeon maintained the film programmes, and booking of tickets online and by telephone. This gave customers the opportunity to watch operas on the giant screen. The BFI retained power over the cinema's operation however, including parts of the film schedule, the name and the technical operation.[7]
To start this move to mainstream cinema, the BFI London IMAX theatre celebrated by having sold 66,000 pre-booked tickets for The Dark Knight Rises in just 5 weeks, giving a total sale in tickets of £1,000,000 even before the premiere of the movie.
In June 2022, the BFI announced that its ten year concessions deal with Odeon would end on 19 July 2022, with the BFI regaining control of operations. The cinema closed on this date, with a planned re-opening on 22 July.[8]
Screen size comparative to other London large screens
The BFI IMAX is the largest cinema screen in the United Kingdom. It measures 25.9m (85 feet) wide by 19.8m (65 feet) high with a total screen size of 512.8m² (289m² for a 2.39:1 film, 363m² for a 1.85:1 film, 469m² for an IMAX 1.43:1 film).[9] Before its October 2022 refurbishment it measured 26.5m wide by 20m high, which meant that if showing a film with an aspect ratio of 2.39:1, only 293m² of the screen will be in use, or 379m² for a 1.85:1 film, or 491m² for an IMAX 1.43:1 film. The auditorium seats 493, including 4 wheelchair spaces.[10]
