Marni Nixon’s voice is the one behind some of cinema’s most unforgettable musical moments, even if her face remains less familiar. Known as the “ghostess with the mostest,” she famously dubbed the singing voices of iconic characters like Maria in The Sound of Music and Princess Anna in Disney’s Sleeping Beauty. While actresses like Julie Andrews and Audrey Hepburn brought these roles to life on screen, it was Nixon’s soaring soprano that carried the songs, blending seamlessly yet leaving a lasting impression. Working with directors like Robert Wise and Disney’s animators, her behind-the-scenes contributions made classics sing with unforgettable clarity, quietly shaping how we remember these films today.
