While filming the scene where Ruby Cruz's, Zoey Deutch's, and Jonah Hauer-King's characters actually engage in a threesome, the three actors kissed for six hours.
The director's own children play the niece and nephew of Olivia (Zoey Deutch) character. The script called for 2 and 4 year old and Chad's children were the exact same age.
The movie was filmed on location in Little Rock, Arkansas, which is also where the majority of the film takes place. The script originally had New Orleans, Louisiana as the film's primary setting. The producers chose Little Rock as their filming location because Arkansas had competitive incentives for the production. Arkansas also has had restrictive abortion laws since 2022, which was crucial for the sake of the story.
