Michelle Williams reportedly earned about 1 percent of Mark Wahlberg's salary during reshoots for "All the Money in the World."
The actress was paid about $80 per day to reshoot scenes including Kevin Spacey, totaling less than $1,000, according to USA Today.
Wahlberg, meanwhile, earned $1.5 million.
Both actors are represented by the William Morris Endeavor agency. Reps for the two did not immediately return requests for comment.
"All the Money in the World," about the kidnapping of the 16-year-old son of oil tycoon Jean Paul Getty, was reshot with Christopher Plummer replacing Spacey after he was accused of sexual assault by multiple men.
Director Ridley Scott previously told the Daily News that he made the decision to remove Spacey "immediately."
"Honestly, within about 22 hours I was on the phone with my partners and was saying, 'We gotta replace this, and I know who can do this. Is he available? Let's get into it,'" he said.
Scott told USA Today in December that he "refused to get paid" and that "everyone did it for nothing," but that appears to be untrue.
The large pay gap between Williams and Wahlberg drew the attention of many online.
"How on God's green Earth does Wahlberg not read the room, there? No way he doesn't know everyone else is doing it for free. He makes like $100m a year _ how do you not tell your agent to let this one go?" "Good Place" creator Michael Schur tweeted.
"If he isn't told to donate $1.5m to RAINN or Planned Parenthood or some other non-profit in the next 48 hours, he should fire his publicist."
Jessica Chastain commented on early rumors about the difference as well.
"I really hope that with everything coming to light, she was paid fairly," she tweeted.
"She's a brilliant actress and is wonderful in the film."
Busy Phillips called the reports "shameful" and Judd Apatow said it was "so messed up that it is almost hard to believe."
"I wonder if the studio or Wahlberg will do something to make the situation less insane," he tweeted.
