Surprisingly powerful despite its cute premise, Horrocks shines as a timid young woman (known as Little Voice) who has the uncanny ability to unerringly reproduce the voice of dozens of great female vocalists (eg. Garland, Bassey, even Marilyn Monroe). Smarmy promoter Caine puts her onstage, where her neurosis only worsens, but not before a few sparkling hours before the crowds.

Horrocks deserves far more praise than she got for this role, considering she performed all the phenomenal music for the picture. Caine is great as well, ditto Blethyn as LV's self-centered mother.
