BFI IMAX

It is a six-story glass cylinder sitting isolated in the center of a busy Waterloo roundabout, effectively an island accessible only by underground pedestrian tunnels. Despite the heavy traffic circling the perimeter and the London Underground running just meters below the foundation, the auditorium remains sealed off from the noise. The entire 5,300-ton upper structure rests on a system of anti-vibration bearings and springs, a necessary engineering feat to keep the rumble of the subway from shaking the UK’s largest cinema screen. Inside, the scale is aggressive. The projection surface stands 20 meters high – roughly the height of four double-decker buses – and the seating rake is exceptionally steep to accommodate it. This is not a standard multiplex setup; the room feels built entirely in service of the image. While it operates a modern 4K Laser system for most screenings, the booth still houses a rare 15/70mm film projector. When directors release features shot on IMAX film, this is one of the few places capable of showing them in their intended 1.43:1 aspect ratio, filling the canvas from floor to ceiling. The sheer verticality of the image dictates where you should sit. Regulars know to avoid the front entirely to prevent neck strain, aiming instead for the back third of the house – specifically rows L through P – where the geometry lines up best. Legroom is tight and the lobby areas are functional rather than luxurious, but the trade-off is the highest-resolution analogue projection available in the country.
