Reference excerpt

Someone Behind the Door (French: Quelqu'un derrière la porte) is a 1971 French crime-drama film directed by Nicolas Gessner. In the UK, it was twice retitled as Two Minds For Murder (theatrical title) and Brainkill (VHS title). It is based on a novel by Jacques Robert. The film was shot on location in Folkestone, England.

Plot A neurosurgeon and psychiatrist manipulates an amnesiac to murder his wife's lover, believing that the patient will have no memory of what he has done, providing the surgeon with a perfect alibi.

Cast

Production

Filming Almost all of the film was shot at various locations in Folkestone. Key locations include Folkestone Harbour and Beach.

Controversy When Charles Bronson appeared on the Dick Cavett Show, with fellow guests Richard Attenborough and Jill Ireland (Bronson’s wife) he confirmed that this was one story about his attacking a director that was true. On the last day of filming his frustration at the director, who he believed had stuck doggedly to a poor plan of how to film the story, boiled over, he grabbed Nicolas Gessner by the throat, and gave him a shake. Jill Ireland confirmed this and agreed with Bronson’s assessment of Gessner, “He was a bit thick”

Worked examples

Example 1 — a first encounter with Someone Behind the Door

Start with the simplest possible case. Write down what Someone Behind the Door claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Someone Behind the Door before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Someone Behind the Door ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Someone Behind the Door

In research: Someone Behind the Door appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Someone Behind the Door in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Someone Behind the Door is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1970s French film stubs, 1970s psychological thriller films, 1971 English-language films, so understanding it makes those chapters shorter.
In everyday life: Look for Someone Behind the Door outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
