History in Technicolour is a conversation about historical films and what happens to history once a filmmaker gets hold of it. Wolf O'Neill and David Crowther are the two regular voices. They take a film, talk it through as cinema, then hold it up against the past it claims to show. The titles cover a lot of ground: Gladiator, Oppenheimer, The Great Escape, Chariots of Fire, Bright Star and Napoleon. That puts Roman power politics, the atomic bomb, a prison camp and a period romance side by side. The history is taken seriously without going stiff. On Oppenheimer, the talk turns to the film's rallies, protests and letters from scientists asking that the bomb not be finished or not be dropped, and to the scientists who quit rather than take part. On Gladiator, the discussion works through why an enslaved ex-general could still command loyalty, and how the army stood apart from the Senate. Partway through, one speaker admits to generalising and is told they are actually right. On Chariots of Fire, one wandering accent turns into a short discussion of the assumptions people attach to posh, northern and Estuary voices. Napoleon gets different treatment. It is a recent release, which the show does not always cover, and Henry Theodore Logan joins the pair for it. The main complaint is scope: a biopic that tries to go from soup to nuts has too much history to get right. Still, the same voice describes coming round after a painful first fifteen minutes and deciding the film works better as a study of obsession and megalomania than as a record. Disagreement is part of the appeal. Wolf picks The Great Escape partly to see whether David will dislike it. Chariots of Fire ends on an admitted difference of opinion. Bright Star, Wolf's pick, sends David, who likes his films to have laughs or death, into a romance he ends up enjoying. The detours are half the fun. There is a spat over the word 'stoked', a joke that Barbie is just a plastic toy, and a verdict that the camp in The Great Escape looks rather like Butlins. A question about which role to take in an elaborate prison escape, forger or scrounger, gets a confession of total practical uselessness in reply. Two Christmas editions choose films likely to be on television over Christmas Day and Boxing Day, and one ends with a list of favourite Christmas dinner trimmings. Listeners are invited onto Facebook to argue back. For a first listen, Oppenheimer is a good way into the history side, and The Great Escape shows the pair at play.
