Los Angeles (CNN) -- The Screen Actors Guild Awards -- the only industry honors that solely recognize performers -- will bestow trophies Sunday night.

Among the actors who will honor their colleagues at the ceremony in Los Angeles will be George Clooney, Tina Fey, Meryl Streep and Michelle Williams.
Leading the way in nominations this year is "The Help," with four.
"The Help," which tells the story of the treatment of maids in a Mississippi town during the civil rights era, is competing for best movie cast, while Viola Davis was nominated for best actress and Jessica Chastain and Octavia Spencer are both competing for best supporting actress.
"The Artist," a French movie about the silent film era, received three nominations including best cast. Jean Dujardin was nominated for best actor and Berenice Bejo for best supporting actress for their work in the film.
The other best movie cast competitors include "The Descendants," "Bridesmaids" and "Midnight in Paris."
"The Descendants" also garnered a best actor nomination for George Clooney.
