Jon Snow journalist returns to Channel 4 with Jon Snow: A Last Big Story, a feature-length documentary that follows him while he lives with Alzheimer’s disease and pursues a toxic waste disaster in Zambia. The film does not treat his diagnosis as a side note; it puts memory loss inside the reporting itself, which is the point.
“Strange old business, life,” he says at the outset, then later adds, “I feel I’ve witnessed a great deal.” Those lines carry the film’s core proposition: a veteran broadcaster of 50 years is still working, even as his own recall is being tested on camera.
Jonathan Rohrer and the memory test
Jonathan Rohrer asks Snow to retain the words “bus, door and rose” for a few minutes, and Snow cannot repeat them when asked later. That sequence is the film’s sharpest practical detail because it shows the condition in motion rather than as background commentary. It also explains why the documentary matters as more than remembrance: it captures the mechanics of memory loss inside an active work setting.
The film looks back through clips from his broadcasting career while keeping him in the present tense. Precious Lunga, his Zimbabwean wife, is part of the story too, and she says, “Hiding him away would be stifling his life before it’s time.”
Zambia, Ben and the Kafue River
During a regular trip to Africa with Lunga, Snow was told about a dam collapse at a Chinese-owned copper mine in Zambia that leaked toxic waste into the Kafue River. He then set out with Ben, his old producer from Channel 4, to cover the story. Snow puts it plainly: “You don’t often go on one story and find you’ve found another.”
That is where the documentary becomes a business story as much as a personal one. A familiar broadcaster’s return gives Channel 4 a subject with built-in authority, but the film also uses that authority to push an environmental crisis into view, and the story says his persistence helped bring global attention to it.
Five years after retirement
Five years after his retirement, Snow is back on Channel 4 in a role that combines memoir, diagnosis and reporting. He also appears with Katie Razzall, described in the film as a protege of his at Channel 4, and he does not seem to remember that he had already been investigating the Zambia story in that sequence.
The documentary’s value is straightforward: it gives viewers a working journalist, not a retrospective tribute. The question it leaves hanging is how far his memory loss has shaped the reporting beyond the scenes shown here, because the film proves he can still chase a major story even when he cannot always hold the last one in mind.
