Wahlberg's lawyer vetoed Plummer's casting in a letter to the film's financiers, saying the actor would only agree if he were paid the extra money.
Although Wahlberg is yet to respond to the latest reports, they come after it was reported that Michelle Williams was paid less than $1,000 (£730) for the reshoot.
"I'd be wherever they needed me, whenever they needed me", she said. "She's a brilliant Oscar nominated, Golden Globe winning actress".
TMZ also reported Thursday that Scott was unaware Wahlberg renegotiated his fee and feels he was "hung out to dry" after having told press the entire cast returned for free. He added: "They all came in free".
Pay discrepancies are sadly nothing new in the entertainment business, or anywhere really, but they rarely get this egregious.More news: Great Britain's Winter Olympics team challenged to secure at least five medals
Coming at a moment when, under the new Time's Up banner, actresses are calling for gender equality, the report appeared to present an extreme case of a male actor being lavishly rewarded while his female co-star was expected to work for less than one percent of his salary. "But Michelle, no. Me, no".
She lost out at the Golden Globes on Sunday to Frances McDormand, but proved to be the flawless date for her guest, #MeToo creator Tarana Burke. "Because I appreciated so much that they were making this massive effort".
That's when Burke chose to take action by helping the communities where rape crisis centers and sexual assault workers were not present, and "Me Too" was born.
At around the same time, we're told Ridley flew to London to see Mark and convince him to do the reshoot.
