Adding to the anger, Mr. Scott had previously said that the actors did the reshoots “for nothing” — meaning union minimums — and Ms. Williams and Mr. Wahlberg are both represented by the William Morris Endeavor agency.

The disclosure of specific salary details also came just after Sunday’s Golden Globes, which was a showcase for Time’s Up, a new initiative to end sexual harassment and gender inequality in Hollywood and other industries. Ms. Williams, who earned a Golden Globe nomination for her role in “All the Money in the World,” walked the red carpet with Tarana Burke, senior director of the nonprofit Girls for Gender Equity and the founder of the #MeToo movement.

Most contracts with actors include a certain number of reshoot days as a routine stipulation. If additional filming is needed, actors will make themselves available — as their schedule allows — to clean up scenes. But Ms. Williams and Mr. Wahlberg, both of whom had agreed to appear in “All the Money in the World” for less than their standard fee, took different approaches to the reshoots, according to the people briefed on the matter.

Because of the circumstances, Ms. Williams quickly agreed to return. The people briefed on the matter said that she did so believing that other participants had made the same decision. She ultimately worked over Thanksgiving, racing to London on an overnight flight after arranging for her 12-year-old daughter, Matilda, to spend the holiday without her.

“They could have my salary, they could have my holiday, whatever they wanted,” she said of the production team at the time. “Because I appreciated so much that they were making this massive effort.”

Although several actors with small parts, including Timothy Hutton, had agreed to return for reshoots for minimum pay, Mr. Wahlberg was not one of them, according to the people briefed on the negotiations. He asked his primary agent, Doug Lucterhand, to push for more money. (Ms. Williams is represented at William Morris Endeavor by Brent Morley.) Mr. Wahlberg was already not thrilled to have worked for roughly 80 percent less than his standard fee, the people said, especially since overseas distributors were using his box office track record to promote the film.

Because Ms. Williams had already committed to return, Mr. Wahlberg had leverage over the production team: He was the only major missing piece, and the clock was ticking. The finished film was set to be released in theaters on Dec. 25.
