The Black Sheep of Whitehall
1942 film by Basil Dearden, Will Hay
The Black Sheep of Whitehall (the opening credits read Black Sheep of Whitehall) is a 1942 British black-and-white comedy war film, directed by Will Hay and Basil Dearden, starring Will Hay, John Mills, Basil Sydney and Thora Hird in her screen debut. It was produced by Michael Balcon and Ealing Studios.
Plot
When he is forced to vacate the office of his debt-ridden correspondence college, 'Professor' Will Davis goes to the Ministry of International Commerce at Whitehall in order to confront his one-and-only student, PR man Bobby Jessop. To get Davis off his back, Jessop proposes to get him a job at Whitehall. Jessop then leaves in order to fetch a Professor Davys at the railway station. The professor is a leading economist who has returned from a long stay in South America in order to advise the British government on a trade treaty with the South American nations, which could be crucial to Britain's war effort.
The clueless Davis is mistaken for the expert and gets involved in a series of interviews, giving answers based on gambling, con jobs, double entendres or just plain ignorance. These scenes are very funny and are made more so by the reactions of an increasingly incredulous Joss Ambler as government minister 'Sir John'. Jessop later returns with 'Professor Davys' and the confusion is sorted out, though it has left the BBC interviewers in a state of mental collapse. Jessop then discovers that the man he brought with him is in fact Crabtree, a member of a group of fifth columnists working for Nazi Germany.

Why this record matters
The phrase “1942 film by Basil Dearden, Will Hay” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Attribution, date and provenance are strongest when supported by the original work, a catalogue record and documented transmission. The source revision retrieved here is dated Feb 20, 2026. The linked authority identifier is Q7718439. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1942.
Later fame can flatten the distinction between original context, subsequent adaptation and institutional collecting history. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
