Black comedy Three Billboards Outside Ebbing, Missouri won three prizes at the Screen Actors Guild (SAG) awards on Sunday in a ceremony marked by women and their stories amid the sexual misconduct scandal that has swept Hollywood.
The Fox Searchlight film about a furious woman seeking justice for the murder of her daughter was named best ensemble, the top SAG honor.
Frances McDormand won best actress and Sam Rockwell took home the best supporting actor statuette for their roles in the film.
Britain's Gary Oldman won best actor for playing wartime leader Winston Churchill in Focus Features' Darkest Hour, while Claire Foy won best supporting actress for her role as Queen Elizabeth in the Netflix hit series, The Crown.
The SAG awards are indicators of likely Oscar success in March because actors form the largest group of voters in the Academy of Motion Picture Arts and Sciences.
Oscar nominations will be announced on Tuesday.
