The “Noah” epic releasing in theaters this Friday (March 28) promises to be controversial, with director Darren Aronofsky calling it “the least biblical biblical film ever made.” As the story of Noah remains near and dear to people of many faith traditions, the film has already unleashed a flood of criticism.

But Aronofsky says every part of the story fits the biblical narrative. He said the story of Noah illustrates a long tension between wickedness and forgiveness. ”All of it’s a test,” he said. “We were trying to dramatize the decision God must have made when he decided to destroy all of humanity.”

In an interview, Aronofsky described where he got the idea for the film, how he plans to respond to critics and why he focuses the film on themes of justice vs. mercy. Some answers have been edited for length and clarity.

Q: Where did the idea for the film come from?

A: I was raised Jewish in Brooklyn. I can’t really remember my first exposure to the Noah story, to be honest. It’s one of those things we’re all taught very, very young. But I got connected to the story in such a deep way when I was in seventh grade. I had this magical English teacher. One day, she said, “Alright, everybody take out a pen and paper, and write something about peace.” I wrote a poem called “The Dove” about Noah. It turned out it was a contest for the United Nations, and I ended up winning the contest and reading the poem at a UN convention a few weeks later. It was the first time I perceived myself as maybe a storyteller. Noah has sort of been this patron saint, because it was the first time I ever really wrote something that won something.

Q: So how did you come back to the story?

A: After I made the film Pi, I was looking for a next film and started thinking about Noah. It didn’t happen for a few years, because Hollywood wasn’t really interested in making kind of a biblical movie. The idea wasn’t around back then, but now it’s very in vogue.

Q: Was this before The Passion of the Christ?

A: I actually first set it up in 2000, so yes. But Hallmark came out with its own Noah film, so we stopped working on it for a while. Our first draft was in 2003, and when the film started to happen, my mom tracked down my teacher, who was 78 years old. I invited her to the set, and she’s actually a one-eyed crone in the movie who says, “You! You!”

Q: Has making the film made a difference for your faith at all?

A: I don’t think it’s changed in any way. I don’t think this has affected it in either way. It’s been more about bringing this story to life and breathing life into it.

There’s a complexity that’s not necessarily written in the words of the Bible but it’s hinted at. The second thing Noah does after the flood is he goes and gets drunk and then has this falling-out with his son. To us that was a huge clue to their relationship. So we started to build a whole story out of that relationship between Noah and Ham and how they got there. That led to this whole idea of good and bad within all of us, and the struggle of righteousness in all of us, to try to balance justice and mercy in our lives. If you look at the film, every character is sort of dealing with these ideas of wickedness and forgiveness.

Q: Is that tension or struggle between good and evil something that plays out in your own life?

A: The idea of original sin is a really interesting story to help us all think about what goes on inside of us, that we all kind of have a sense of the right thing to do, and we all understand what the wrong thing to do is. And we understand that there’s a decision in front of us.
