Separate the venue from the presentation
A large-format cinema can show more than one kind of presentation. BFI’s IMAX listing for Barry Lyndon describes a digital 4K restoration, while other screenings identify film prints. The venue name is therefore not a complete specification of the source or projector route used for a particular event.
Distinguish a release print from camera capture
BFI’s 2025 festival announcement describes Empire of the Sun as shot on 35mm and released in a limited 70mm blow-up form. A 70mm screening label can thus identify the exhibition print without establishing that the film was originally photographed on that gauge. Read the production and screening statements as separate facts.
Check the exact edition and event
Restorations, original release prints and later digital editions may all exist for the same title. Match the advertised screening date and format. An old poster or a review of another presentation does not establish what is being offered now. This is especially useful when a visit is being planned specifically to see a physical print.
Avoid translating the format into an unsupported home claim
A film’s cinema gauge or restoration credit does not establish its current streaming resolution, soundtrack or subscription availability. For home viewing, inspect the actual legitimate release and service conditions. For a cinema visit, use the event’s own format note and ask the venue if it is unclear. Keep capture, surviving material, exhibition and home delivery distinct rather than treating one prestigious label as a guarantee of all four.

BFI provides that example for Empire of the Sun.
