The NFB’s Turn to Heritage: Revisiting Montreal in Luc Bourdon’s <i>La mémoire des anges</i>
Bibliographic record
Abstract
Released in 2008, Luc Bourdon’s La mémoire des anges (2008) consists of footage of Montreal shot between 1947 and 1967, selected from some 120 films in the National Film Board (NFB)’s collection. A product of the NFB’s heritage strategy and of the long struggle for urban preservation in Montreal, La mémoire des anges participates in both the fabrication of the city’s image and the valorization of its heritage. This article focuses on the film’s dual heritage, placing it into the context of today’s global push for cultural preservation—a drive that is in part motivated by urban economies—before analyzing how the film skirts the “heritage discourse,” making selective use of the NFB archives and adopting a formal composition that critically updates the past.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
