A number of incredible stories have emerged about Chadwick Boseman in the aftermath of his tragic passing.
Many praised how the 'Black Panther' star visited children in hospital fighting cancer while he himself was battling colon cancer.
The actress spoke of how Chadwick Boseman, who was a producer on '21 Bridges', actively pursued her for the movie.
She told Empire Magazine: "He was a fan of my work, which was thrilling, because it was reciprocated from me to him, tenfold.
"So he approached me to do it, he offered me this film; and it was at a time when I really didn't want to work anymore.
"I'd been working non-stop and I was exhausted, but then I wanted to work with him."
Not only that but Chadwick Boseman fought for Sienna Miller to get a higher pay to come on board. He even donated a part of his salary to hers.
Miller said: "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.
"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.’
"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."
Continuing to sing his praises, she added: "It was about the most astounding thing that I've experienced.
"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.
"In the aftermath of this I've told other male actor friends of mine that story and they all go very very quiet and go home and probably have to sit and think about things for a while.
"But there was no showiness, it was, ‘Of course I'll get you to that number, because that's what you should be paid.’"
