Chadwick Boseman donated part of his salary to co-star Sienna Miller on '21 Bridges'

One month after his death, stories of Chadwick Boseman's generous spirit continue to come to light.

Sienna Miller, who co-starred opposite the late actor in the 2019 action-thriller "21 Bridges," revealed in a new interview with Empire that Boseman donated part of his salary to her.

"I didn't know whether or not to tell this story, and I haven't yet. But I am going to tell it because I think it's a testament to who he was," Miller began.

"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," Miller explained. "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.’"

"And Chadwick ended up donating some of his salary to get me to the number that I had asked for. He said that was what I deserved to be paid," said Miller, who called the gesture "the most astounding thing" she’d ever experienced during her Hollywood career.

"It's just unfathomable to imagine another man in that town behaving that graciously or respectfully," she said.

Boseman died on Aug. 28 at age 43 after a private battle with colon cancer.
