Theron said her reported feud with Jolie was "100 percent" an instance of the media pitting two celebrities against each other.
"I don't know her very well, I know her from events, but always so lovely," the star said.
"We really don't know each other. We're not friends or hang out. But she's never been nothing but gracious and lovely and warm," she added.
"I did not turn the role of Wonder Woman down," the actress said. "This is a great example of how Hollywood slaps you in the face when you start aging."
"So somebody had said to me, 'Oh, there's action on this thing Wonder Woman. We just want to make you aware of it,'" she recalled. "I'm like, 'I'm just not familiar with it. What does Wonder Woman do?' This person said, 'No, it's for Wonder Woman's mom.'"
"When you do something that's outside your wheelhouse, you naturally function from a place of fear a little bit," she said.
