New York City is a location in all four movies in the An American Tail series. It is the entry point for immigrants coming from Europe, making it very multi-cultural. It is unfortunately a difficult place for mice to live, being controlled by cat gangs, crooked or ineffectual police, and sweatshop owners. It is plagued with poverty, and as evidenced by Orphan Alley, a lot of mice are homeless. It is such a big city that when Fievel was separated from his family it took the whole movie for him to find them. Conditions improve after the Mott Street Maulers are sent to Hong Kong, but in the sequels, they are only replaced by villains who are just as bad.
