Michelle Williams has had one of the most "indelible days" of her life after Mark Wahlberg donated US$1.5 million (NZ$2.07m) to Time's Up.
The 37-year-old actress has spoken out after her All the Money in the World co-star agreed to donate the fee he received for reshoots on the movie to the anti-harassment charity, with their shared agency William Morris Endeavor (WME) donating an additional US$500,000.
It followed a backlash after it emerged Williams was paid just US$80 a day when they returned to shoot key scenes again after Christopher Plummer replaced Kevin Spacey in the film.
But though it's a day she'll never forget, Williams insists the actions are not "about" her, but a stand for equality.
She also sent her support to Anthony Rapp, whose accusations of inappropriate sexual behaviour against Spacey led to the actor being fired from the project.
