A long long time ago I watched a movie starring one of my favorite British character actors, Sir Nigel Hawthorne (the Sir Humphrey Appleby of my childhood, for I was a keen fan of "Yes, Minister") playing George III of England, having one of his spells of mental instability that are thought to have been caused by acute intermittent porphyria: a metabolic disorder in which porphobilinogen, a biochemical precursor in the body's synthesis of heme, accumulates in the urine and sometimes causes it to turn unusual colors.
The 1990s Madness of King George film is keen to show how the court physicians who were all obsessed with some particular physical symptom or method of treatment, something they put all their trust in like, such as giving him purgatives or focussing on his bowel movements, while only one radical new man named Francis Willis seems capable of directly addressing the derangement of his mind.
And yet there's a scene in the film which explicitly shows how the court physicians, despite their trust in physical investigations and treatments, roundly dismiss a piece of physical evidence that they simply have no place for in their formulaic approach to doctoring: King George's piss turns purple, and nobody except the lower classes seems to notice or care. Surely it must mean something? But the physicians blow off the symptom.
