The movie is out on our shores this weekend, several weeks after breaking records in the US.
Hunter, reprising her role from the original movie, said the sequel’s lack of political agenda and feminist qualities are what may have helped it resonate with such a large audience.
“To see a very powerful woman kicking ass on screen and still retaining her femaleness? People are finding that so thrilling and so fulfilling,” she told Metro.
“She’s not pretending to be a man. She is a woman.
“I don’t know if it was part of [director] Brad Bird’s mission to make this a triumphantly feminist message movie but I kind of do feel that’s a by-product.”
She went on: “All of us are so full of conflicts. We are all filled with opposites. And great acting always embraces a certain conflict.
“I think one of the wonderful things about Incredibles 2 is that it has that complexity. It’s full-bodied.
“This is not a political movie. It is first and foremost a movie about human beings.”
Incredibles 2 posted the biggest ever opening weekend for an animated movie in the US, and has made $ 504.4 million in that country alone.
That makes it the highest-grossing animated feature of all time in North America, and now it needs its international total to reach $ 1.3 billion and surpass Frozen as the top-grossing animation ever worldwide.
Incredibles 2 has a 94% rating on Rotten Tomatoes, with an average score of 7.9/10.
The critical consensus reads: “Incredibles 2 reunites Pixar’s family crimefighting team for a long-awaited follow-up that may not quite live up to the original, but comes close enough to earn its name.”
Alongside Hunter, the lieks of Craig T. Nelson, Sarah Vowell and Huck Milner also reprise their roles as the rest of the Parr family.
Incredibles 2 is out on Friday in the UK.
