The Golden Globes went black to shine a bright light on abuse and harassment and it was Nicole Kidman who led the way with an emotional acceptance speech honouring her mother.
The Australian actress, dressed in a black gown, won the first award of the night at the Beverly Hilton on Sunday for her role as a physically, sexually and psychologically abused wife in the TV mini-series Big Little Lies.
Kidman backed the win up soon after with a second Globe for producing Big Little Lies.
The significance of the wins were magnified with the Globes transforming into a platform for Time's Up, a movement exploding in the aftermath of scandals involving Harvey Weinstein and numerous other powerful Hollywood men.
"My mumma was an advocate for the women's movement when I was growing up and because of her I'm standing here," Kidman told the A-List crowd.
"My achievements are her achievements and Antonia Kidman, my sister and I say thank you Janelle Kidman for what you fought for so hard."
A sea of black first swamped the usually vibrant Globes red carpet and then it entered the Beverly Hilton ballroom, with Kidman and other invitees wearing black gowns and suits to support Time's Up.
The Time's Up campaign is designed to support all women and men silenced by abuse, harassment and discrimination not only in Hollywood but across the world.
"The time is up," Oprah Winfrey proclaimed when she accepted the Cecil B. DeMille Award for outstanding contributions to the entertainment world.
Kidman, Adelaide's Bruna Papandrea and Reese Witherspoon, as producers of Big Little Lies, claimed Globes when it won best limited series or TV movie.
The Globes have a patchy record in predicting Oscar winners, but a Globe can give huge lifts to Academy Award campaigns.
The Oscar nominations will be announced on January 23 with the ceremony in Hollywood on March 4.
Hugh Jackman, for The Greatest Showman, and Margot Robbie, for I, Tonya, missed out on Globes.
Australians Geoffrey Rush, as Albert Einstein in the mini-series Genius, and Perth's Katherine Langford, nominated for her performance in the Netflix series 13 Reasons Why, also fell short of Globe wins.
The big winner was Three Billboards Outside Ebbing, Missouri, a film about a mother who purchases billboards to bring attention to authorities' failure to solve her daughter's murder.
It beat the fancied Dunkirk, The Post and The Shape of Water for best dramatic picture.
Three Billboards' star Frances McDormand also won best actress in a drama and writer/director Martin McDonagh won the screenplay Globe.
Lady Bird took best musical or comedy film Globe ahead of Robbie and Australian director Craig Gillespie's I, Tonya.
Lady Bird's star Saoirse Ronan also collected best actress in a musical or comedy, beating Robbie, Judi Dench (Victoria & Abdul), Helen Mirren (The Leisure Seeker) and Emma Stone (Battle of the Sexes).
The Shape of Water's Guillermo del Toro won the directing Globe.
