Nolan gives Gotham a Metropolis-meets-the-Midwest makeover, moving it west to his childhood home of Chicago and building Batman's citiscape around key locations like LaSalle Street, the Chicago Board of Trade and the city's distinctive river network. Over the trilogy he turns over the city's grand limestone monoliths to reveal all kinds of creepy crawlies - an increasingly diurnal bunch of badasses led by Bane, who now switches the axis of evil to Wall Street and New York in The Dark Knight Rises. Frank Miller, who described Gotham as "New York after dark", would be pleased to see it back in its spiritual home, but such is Nolan's world-building skill, no-one will spot the joins.
