Speaking to Empire, she said: ‘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 added: ‘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.’

The American Sniper actress described how the gesture was a ‘testament’ to Chadwick’s character and explained how there was ‘no showiness’ to the offer.
Chadwick, who was a producer on 21 Bridges, approached Sienna to star in the film and told her he was a ‘fan’ of her work which she said was ‘reciprocated, tenfold’.
However Sienna revealed how she had been ‘working non-stop’ and was ‘exhausted’. after starring in films such as American Woman and The Catcher Was a Spy.

When the search intensifies, authorities take the extreme measure of closing all of Manhattan’s 21 bridges to prevent the suspects from escaping.
Sienna plays Frankie Burns – a detective working with Andre while Taylor Kitsch, who plays Ray Jackson, and Stephan James, who stars as Michael Trujillo, are the two suspects on the run.
