Lawrence, who won an Oscar for her role in the 2012 film Silver Linings Playbook, had told the BBC presenter she had been filming in a location where there were “sacred rocks”.
“You’re not supposed to sit on them because you’re not supposed to expose your genitalia to them,” she said.
“I, however, was in a wetsuit for this whole shoot so – oh my God, they were so good for butt-itching. One rock that I was butt-scratching on ended up coming loose.
“It was a giant boulder and it rolled down this mountain and almost killed our sound guy.”
She added: “His whole station got destroyed, it was a huge dramatic deal and all the Hawaiians were like ‘Oh my god, it’s the curse’. And I’m round the corner going, ‘I’m your curse – I wedged it loose with my ass’.”
