How we work
Sources and Methodology
Every guide in this library rests on the same procedure. This page sets it out in full, including the kinds of evidence we will not accept and the limits we place on our own conclusions.
Our hierarchy of sources
Not all evidence is equal, and a publication about hidden details has to be explicit about ranking. We work down this order and prefer the highest available level.
First: production records and archives. Set plans, correspondence, call sheets, design documents, continuity paperwork, and prop material held in institutional collections. Several major film archives are held by universities and museums, and their holdings are the most reliable evidence available.
Second: first-hand accounts from the people responsible. Recorded commentary tracks, filmed interviews, oral histories, published memoirs, and technical articles written by department heads. Preference goes to accounts given close to the production and to statements repeated consistently over time.
Third: published screenplays and drafts. A detail present in the shooting script was planned. A detail absent from the drafts arrived later, which tells you something in itself.
Fourth: contemporary trade and technical press. Reporting published while a film was in production, and technical journals covering cinematography, effects, sound, and design.
Fifth: scholarly and museum work. Peer-reviewed film studies, museum exhibition material, and restoration documentation, particularly for older films where memory has become unreliable.
Sixth: the film itself. Direct observation establishes that something is on screen. It never establishes why.
What we do not treat as evidence
Aggregated trivia listings, unsourced encyclopedia entries, forum posts, social media threads, and video essays that cite no primary material. These can be useful for finding a lead, and a lead is not a source.
Claims that circulate widely without an origin. If we cannot trace a statement to someone who was in a position to know it, we either leave it out or state plainly that it is unverified and widely repeated.
Interviews given decades after the fact that contradict contemporaneous records. Memory reorganizes itself, and filmmakers are not immune. Where accounts conflict, we say so rather than choosing the more entertaining one.
How the two labels are applied
Every detail in every breakdown carries one of two labels. Confirmed requires support at one of the top five levels above. Interpretation covers everything else, including readings we find persuasive.
An entry can be labeled confirmed for one claim and interpretation for another, and our guides split them where necessary. It is common for a detail to be verifiably present and its purpose to be entirely undocumented, and that combination is exactly where most bad film writing goes wrong.
We do not use a third label for likely. A publication that grades its own confidence in five steps ends up asking readers to do its work.
How we handle timestamps and versions
Every time given in a guide is approximate and is stated as such. Running times differ between theatrical cuts, international releases, extended editions, television edits, and restorations, and a detail can shift by several minutes or disappear entirely.
Each guide names the version it describes and gives its approximate running time, so you can tell whether the copy in front of you should match. Where a detail exists in only one version, the guide says which.
We give times in whole minutes rather than to the second. A guide is a signpost for finding a detail, not a frame reference.
Films made outside English
A number of guides here cover films not made in English, and several details in them are fully legible to a domestic audience and invisible internationally. We treat that gap as part of the subject rather than as a problem to smooth over.
Where a detail depends on wordplay, a local song, a regional custom, or a piece of national history, we explain the reference rather than merely naming it, and we identify the material we consulted. Where a claim rests on translated interview material, we say so.
Artwork, images, and copyright
This publication does not reproduce frames, posters, promotional artwork, or character designs from the films it discusses. Every image on the site was created for this publication or is used with permission or from the public domain.
We do not reproduce synopses from other publications, transcribe extended dialogue, or publish screenplay extracts. Where a line is essential to explaining a detail, we describe it or quote briefly for commentary, which is the purpose this publication exists for.
All film titles, characters, and trademarks remain the property of their rights holders. See the independence disclaimer for our position on affiliation.
Why guides carry two dates
Each guide shows when it was first published and when it was last updated. Both dates are real. We revise guides when new first-hand material appears, when a reader supplies a documented source, when a restoration changes what is visible, and when we find an error.
Substantive changes to a factual claim are noted on the page. Corrections of the record are handled under the corrections policy, which sets out what we disclose and when.
