A 1964 NFB biographical documentary about a dead surveyor should be a snoozefest, but there's something deliberately mythic happening here—Devlin treats mapmaking like metaphysics, which is either pretentious or genius, and I'm genuinely unsure which.
Devlin situates Thompson within the grand documentary tradition of the NFB's golden age, where historical inquiry becomes formal meditation; the contemplative pacing and the way geography transforms into philosophy feel like they know exactly what lineage they're inheriting.
The choice to let surveying itself—those lines, measurements, the act of naming emptiness—become the film's visual and narrative center is what makes this work; it's a budget film that understands its subject well enough to film *ideas* instead of just events.
