The Detection Club looks like it might be fun, but I wonder about one thing: Why did the creators decide to make Miles Jupp look exactly like Chesterton but make Bryony Hannah and Cara Theobold look nothing like Christie and Sayers?
For the record: Christie was tall (5'8", unusual for the time) and fair, and somewhat formal in her public appearance; Hannah is short, dark, and petite, and is dressed like a dumpy schoolmarm. Sayers was also often called tall (though there’s no record of her actual height), increasingly stout from her late 20s on, with short dark-brown hair and a flamboyant eccentricity of dress often remarked on; Cara Theobold in the show is bright blonde and almost a fashion plate.
There’s no reason why the show should adhere to the facts in this matter — but it’s so particular about getting GKC right (the hair, the pince-nez, the cape)! I find myself thinking that she show would be more visually interesting if Christie’s traditionalism were contrasted to Sayers’s eccentricity.
