When Lawrence first read the script to "Mother!" in a New York City hotel, she found it so upsetting that she threw the script across her room, calling the writer and director Darren Aronofsky "crazy."
But she later found love with him after making his movie.
Imagine a film so intense that watching the finished product even scared the star, who plays the lead.
"I was really shaken, and I thought 'We've gone too far. This is too far. It's too much,'" Lawrence said.
In "Mother!" Lawrence has the title role of the wife of a poet with a bad case of writer's block known only as "him" and played by Javier Bardem.
"'Him' being this selfish, strong individual kind of character who destroys more than creates," Bardem said.
For those used to Lawrence playing strong women such as Katniss Everdeen in "The Hunger Games" series, her passive role here amid so much mayhem will come as a surprise. She says the role was a departure with a high degree of difficulty.
"There was one scene I hyperventilated too long, and I tore my diaphragm, and I think I popped a chest rib out," she said. "So yeah, I lost total control of myself."
There's talk of another Oscar nomination for Lawrence, and she is now in a relationship with Arnofsky, a Brooklyn native.
"When you do your work with truth and honesty, I don't think there's anything to worry about," he said.
"Mother!" opens in theaters September 15.
