Theron developed the film herself, after deciding to pursue a part she wanted: "I wanted something very specific... I was about to turn 40 so I decided to take matters in my own hands and actively go after something."

Praising films like Wonder Woman, she also asked fans to watch and help support female-led films to convince Hollywood bosses they're worth making.

"We're just as good as the guys - plus we have boobs!" she joked.
