Riley Keough recalled a scary incident on a movie set.

The Daisy Jones & The Six star opened up about how eating a granola bar could have endangered the life of her co-star Andrew Garfield while on the set of their film Under The Silver Lake.

The actress, 34, who recently talked former step-dad Michael Jackson's Neverland Ranch, was taking a walk down memory lane with Vanity Fair, when a photo of herself and Garfield came up.

'I have a memory on this set where it was actually very stressful,' she began.

'I was in the makeup trailer and I was eating, like, a granola bar or something, and I was about to shoot a scene where I have to kiss Andrew,' she explained.

'The makeup lady was like, "Are there peanuts in that?" And I was like, "I think. I don’t know."'

'And then she like, ran away.' 

Riley was stymied by the action, but the stylist quickly returned with a producer, who alerted her to the potentially fatal situation.

'The producer came in and was like, "Riley, Andrew's very allergic to peanuts and we have to shut the set down. They shouldn't have been at craft [services, the on-set catering], and I don't know why they're on set."'

'I was kind of like, "Oh, f**k, that’s crazy,"' the shocked star said.

'But also, like, thank God that this woman caught it, ‘cause I had no idea.'

Under The Silver Lake is a dark comedy that follows an aimless young man in Los Angeles who stumbles upon various conspiracies while investigating the disappearance of his neighbor, played by Riley.

The actress said, except for the scare, she enjoyed working on the film not only because of the cast and crew, but because of its location. 

'This was a very cool movie to film because it was in Los Angeles, and I’ve only ever been able to film three things in Los Angeles, which is where I live.'

The Terminal List actress recently revealed the name of her one-year-old daughter, whom she shares with husband Ben Smith-Peterson. 

The couple welcomed the little one via surrogate last August, but kept her arrival under wraps until she was mentioned in a letter Ben read for Riley at her mother Lisa Marie Presley's funeral last January. 

The girl's name is Tupelo Storm.

Tupelo was the birthplace of her grandfather, Elvis Presley, and Storm was the middle name of Riley's late brother Benjamin, who passed away in 2020. 

Riley stepped behind the camera to make her directorial debut for War Pony. 

She and fellow director Gina Gammell co-helmed the project about two young Oglala Lakota men growing up on the Pine Ridge Reservation in South Dakota. 

The film debuted at the 2022 Cannes Film Festival and won the Camera d'Or.

War Pony opened in select theaters July 28 and can be watched at home via purchase or rental on various streaming platforms.
