“It makes me so happy because I said from the very beginning that all I want is for Harley Quinn to be one of those characters the way… like Macbeth or Batman always gets passed from great actor to great actor,” Robbie told MTV News in October.

Margot Robbie continued: “I feel like, in not so many cases, are there female characters – Queen Elizabeth I…which I got to have a crack at as well, which I was honoured to do. I was like, ‘Wow! Cate Blanchett did Queen Elizabeth I."

"Now I get to.’ It’s such an honour to have built a foundation strong enough that Harley can now be one of those characters that other actors get to have a go at playing. And I think (Lady Gaga) will do something incredible with it.”
