"She comes from a great legacy, but I also don't think that you want to be defined by the weight of all of that stuff," Theron said. "And I just really admired that she came in and really auditioned for this and was prepared and ready, and she handled this as an individual really well, as an actor really well, and I was impressed by that."
Theron also opened up about how her life-long feminism has affected her parenting style when it comes to raising her two children, son Jackson and daughter August.

"I feel like I was lucky enough to have a parent that was very much aware of female issues and just always raised me knowing that there were no limitations just because of my identity and who I was," she explained. "And, for me, I think it really kicked in in the early '90s, when rape became a big issue in South Africa, and I felt compelled once I got the information and the knowledge about what was happening in South Africa to actually go down there and try and do something about it."
"I feel like I wake up in the morning with my kids and these are things that we kind of apply to our everyday life," she said. "We'll be driving in the car and I'll be like, 'You know you guys can be anything you want?' And they'll be like, 'Ugh, we know, Mom.'"
As for the premiere itself, Theron stunned on the red carpet, stepping out in a gorgeous white Dior suit. She told ET that the fashion house made it for her and she "absolutely loved it."
