Actor Michelle Williams has opened up about being paid significantly less than her "All the Money in the World" co-star Mark Wahlberg for the film's reshoots.

The 38-year-old actor, who joined Speaker of the US House of Representatives, Nancy Pelosi, and other members of the Democratic Women's Caucus to mark Equal Pay Day on Tuesday, credited Jessica Chastain for spreading awareness about her case. Williams said she was "paralysed in feelings of futility" when she learned that Walhberg was paid USD 1.5 million compared to her paycheck of less than USD 1,000 for reshoots after Kevin Spacey's firing from the project, according to Entertainment Weekly.
