AMetropolis is a fictional port city located somewhere on the eastern seaboard of the U.S. Where exactly varies depending on the source. The four superman movies made in 1978, 1980, 1983, and 1987 staring Christopher Reeve, do not specify its location, but based on the existence of various real-life landmarks such as the Statue of Liberty, it must be a stand-in for New York City. In the DC Comics Universe, it is considered to be in New York State (which also is said to be geographically larger than its real-life counterpart). Some sources had previously placed Metropolis on the shore of Delaware Bay in the state of Delaware, across from Gotham City (from the Batman universe). However, this has been superceded by more recent continuity. In the latest Superman movie, Superman Returns, when Lex Luthor unveils his plan on a series of maps, Metropolis can be seen located on a Northeastern U.S. map exactly where New York City would be. (Also, on a side note, Long Island is not present at all.) In the TV series "Smallville," Metropolis must be located either in Kansas, or close by in a neighboring state, as the show has established that 1, Smallville is in Kansas, and 2, Metropolis can be seen from town on clear days in the distance.
