"Two years ago I had an image in my mind of girls in bikinis and ski masks robbing tourists, so I started trying to build narrative around that. If these girls existed, how would they exist and where do they come from? Then I started thinking about spring break and started building the story that way."
He went to Florida and wrote the screenplay during an actual spring break, when the director, who famously wrote the screenplay for Larry Clarke's similarly themed Kids at the age of 19, witnessed teenagers letting loose first hand.
"There were kids puking on my door ... lighting shit on fire," he recalls. "There were midgets having sex on chandeliers; I found a jawbone in a carpet. It's pretty crazy."
Ultimately, Korine says, the film is about female empowerment and the new generation of kids he was keen to examine.
"It's a new vision. It's about kids who have been raised on video games and YouTube clips, so the step from watching and viewing to doing something is sometimes very, very small."
Since Kids and his subsequent directorial efforts, Korine's edgy reputation made the three young actresses clamour to work with him.
Still, megastar Gomez, as the religious Faith, stays on the sidelines of the torrid, sexually charged story.
"I just didn't think I was ready for it," admits Gomez. "I do think that Faith was right for me at this time in my career and in my life so of course I'm going to eventually work up to that, but for what I'm doing right now it was the right choice to make."
Nevertheless, her portrayal sent shock waves to her fans. "I do everything for my younger fans and this one was more for me in a way. Harmony got us to do things I didn't think I was able to do.
"I didn't think I would ever be able to smoke a bong. But it's good we had that trust in him and it obviously paid off."
For Hudgens, who is known from Disney's High School Musical trilogy, Spring Breakers was "an exciting ride".
"That's what's so brilliant about acting, is finding these different characters and being thrown into new situations. Personally I don't think I'd be thrown into what the girls go through," she giggles, "but overall I will always look back on the film as a piece of art and something I'm so proud of."
