Where was "West Side Story" primarily filmed?

"West Side Story" was primarily filmed at Lincoln Center, which is a significant cultural complex located on the Upper West Side of Manhattan. The choice of Lincoln Center as a filming location is meaningful because it embodies a vibrant artistic scene, much like the thematic essence of the musical. It provided a visually stunning backdrop that complements the story's dynamic relationship between the characters and their urban environment.

The other locations are noteworthy in their own rights, but they do not hold the same connection to the essence of the film. Times Square, while an iconic landmark, is more associated with entertainment and commercial activity rather than the specific narrative focus of "West Side Story." The Bronx and Brooklyn Heights also have their own cultural identities; however, they did not serve as the primary sites for this film’s production, which was heavily centered around the themes of community and rivalry within a distinct urban environment captured best at Lincoln Center.
