真的有高潭市的？

没有，高潭市是以纽约为原形的，不过比纽约繁华4倍，这是最接近的答案Historically, "Gotham" is a nickname for New York City, first used by Washington Irving in the early 19th century. For most of the publication history of Batman in comics, Gotham has been assumed to be a New York City analogue;Frank Miller has said that "Metropolis is New York in the daytime; Gotham City is New York at night."DC Comics president and publisher Paul Levitz says that Gotham is "New York from 14th Street down, the older buildings, more brick-and-mortar as opposed to steel-and-glass." However, longtime Batman artist Neal Adams considers Gotham to be based on Chicago (whose nickname is "New Gotham"), pointing to its history of corruption and organized crime, and adding, "One of the things about Chicago is Chicago has alleys (which are virtually nonexistent in New York). Back alleys, that's where Batman fights all the bad guys."Film adaptations have varied: Tim Burton's Gotham was based primarily on New York, while the films directed by Christopher Nolan have shown a Gotham more closely based on Chicago.

这是w ikip edia上的，new york的确有过gotham的外号，不过蝙蝠侠里的gotham是纽约还是芝加哥是有争 议的，最后一句说提姆伯顿的蝙蝠侠以纽约为原型，而诺兰的版本则更接近芝加哥。
