Ask what the dataset is recording
The BFI Filmography FAQ explains that its project draws on records of films released to UK cinemas and captures information including release date, production countries, companies, runtime and credits. A date in that context is serving a defined research purpose. It should not automatically be substituted for the year printed in every international catalogue or production-history discussion.
Preserve the label beside the number
When collecting information about a film, write production year, festival date or UK cinema release date rather than recording a bare year. A database may contain several relevant dates for the same work. Losing the field name makes later comparisons difficult because an apparent disagreement can simply be two sources answering different questions. The source’s stated scope is part of the information, not optional decoration.
Resolve a search without inventing a new film
Suppose a viewer remembers a release around one year but finds a matching cast and director under another. Compare the title, credited people and stated release context before deciding they found a remake. Do not merge records solely because the names match either. The correct next step is to establish which event each date describes and whether the records refer to the same work.
Separate identity from the edition being offered
Once the film is identified, a current viewing listing still needs its own edition, audio and access checks. A historical UK release date cannot prove that a particular restored version is available now. Keep the original source reference with any correction you make to a watchlist so another household member can understand why the year differs without having to repeat the whole search.
Questions, answered
Can two different years describe the same film accurately?
Yes, when they refer to different documented events or fields; check each source’s definition.
Does matching the film year identify the exact streaming edition?
No. Edition and current availability require separate information.
