David Livingston/FilmMagic “This was a pretty big budget film, and I know that everybody understands about the pay disparity in Hollywood, but I asked for a number that the studio wouldn't get to. And because I was hesitant to go back to work and my daughter was starting school and it was an inconvenient time, I said, ‘I’ll do it if I'm compensated in the right way,’ ” she explained. “And Chadwick ended up donating some of his salary to get me to the number that I had asked for. He said that that was what I deserved to be paid.” “It was about the most astounding thing that I've experienced,” she added. “That kind of thing just doesn't happen. He said, ‘You're getting paid what you deserve, and what you're worth.’ It's just unfathomable to imagine another man in that town behaving that graciously or respectfully.” RELATED VIDEO: John David Washington Honors Chadwick Boseman: 'He Was Responsible for a Lot of Positive Change’ In the action thriller, Boseman played Andre Davis, an embattled NYPD detective who shuts down the 21 bridges of Manhattan amid a citywide manhunt to find two suspected cop killers.
