West Side Story is a 2021 American musical romantic drama film produced and directed by Steven Spielberg from a screenplay by Tony Kushner. The second feature-length adaptation of the 1957 stage musical, which was itself inspired by William Shakespeare's play Romeo and Juliet, it stars Ansel Elgort and Rachel Zegler, the latter making her film debut, with Ariana DeBose, David Alvarez, Mike Faist, and Rita Moreno in supporting roles. Moreno, who starred in the 1961 film adaptation, also served as an executive producer alongside Kushner. The film features music composed by Leonard Bernstein with lyrics by Stephen Sondheim.
