Sienna Miller has weighed into the film industry's gender pay gap debate, saying she thinks women "should be compensated sometimes more than male co-stars".
Miller, who is set for London's West End in the award-winning Tennessee Williams play Cat On A Hot Tin Roof, was asked if she'd experienced the gender pay gap in films, to which she said, "Yes... to a degree where it's staggering."
The 35-year-old actress, who will star alongside Unbroken and former Skins star Jack O'Connell in the play, told The Daily Telegraph, "At the time, I felt grateful, even knowing what (my) co-star was getting."
She added, "You're so leaned on as a woman to promote a film by doing magazine covers, by what you wear on red carpets.
"They rely on that so heavily that you really should be compensated sometimes more than your male co-stars for what you're asked to do."
She joins other actresses who have this year voiced their concern over the gender pay gap in the entertainment industry, such as Scarlett Johansson, Rose Byrne, Jessica Chastain and Natalie Portman, who has branded the gap as "crazy".
