And, well, did you noticed that Bane also knitted in The Dark Knight Rises?
Yup. After Bane takes over Batman's turf and pits the downtrodden lower classes against the ruling elite (so, like, an almost word-for-word summary of Double Town Story), he lets Scarecrow hold trials/executions of Gotham's rich people ... while secretly controlling the whole thing and playing with yarn. Just like Madame Defarge. But it goes much deeper than that.
2 Cities, 1 Tale is really all about how easy and horrible it is to get caught up in a murderous cycle of revenge, which fits perfectly into the movie, in which Talia al Ghul goes after Bruce as revenge for him killing her father. Speaking of which, in the chapter "Darkness" (as in "The DARK Knight"), we discover that the Madame had a secret personal connection to the main hero of the story, ALSO JUST LIKE IN THE MOVIE, where, near the end, Bane turns out to have been Talia's surrogate father. Hell, even Bane's catchphrase, "The fire rises," seems to be lifted directly from one of the novel's chapters, titled "Fire Rises," essentially making The Dark Knight Rises elaborate Charles Dickens fanfiction starring people in paramilitary Halloween costumes. And it didn't win ALL the Oscars because ...?
