"I 100% support the fight for fair pay," Wahlberg said in a statement.

The announcement Saturday came after directors and stars, including Jessica Chastain and Judd Apatow, shared their shock at reports of the huge pay disparity for the Ridley Scott film. The 10 days of reshoots were necessary after Kevin Spacey was replaced by Christopher Plummer when accusations of sexual misconduct surfaced against Spacey. USA Today reported Williams was paid less than $1,000 for the 10 days.

Both Williams and Plummer were nominated for Golden Globes for their performances.

Talent agency William Morris Endeavor, which represents both Williams and Wahlberg, said it will donate an additional $500,000 to Time's Up. The agency said in a statement that wage disparity conversations should continue and "we are committed to being part of the solution."

"Today isn’t about me," Williams said in a statement issued by publicist Mara Buxbaum. "My fellow actresses stood by me and stood up for me, my activist friends taught me to use my voice, and the most powerful men in charge, they listened and they acted."
