FILM: "A boy like that will kill you brother. Forget that boy and find another. One of your own kind, stick to your own kind," demanded Oakland's Rita Moreno playing Anita in the film version of West Side Story (1961). The Bay Area resident, we should point out, also took home the Oscar for her performance in Leonard Bernstein and Stephen Sondheim's re-imaging of Shakespeare's Romeo and Juliet.
