LOS ANGELES (AP) — The Deep South drama "The Help" has won three prizes at the Screen Actors Guild Awards, including best actress for Viola Davis and supporting actress for Octavia Spencer.
"The Help" also claimed the guild's ensemble award, the show's equivalent of a best-picture prize.
Davis and Spencer won Sunday as black maids going public with uneasy truths about their white employers in 1960s Mississippi.
Jean Dujardin won the lead-actor honor for "The Artist" as a silent-film superstar whose career crumbles when the sound era arrives. Christopher Plummer won for supporting actor as an elderly dad who comes out as gay in "Beginners"
