Bret Easton Ellis wrote a screenplay.
Ellis was educated at The Buckley School in California; he then attended Bennington College in Vermont, where he originally studied music then gradually gravitated to writing, which had been one of his passions since childhood
 When Van Sant appeared on The Bret Easton Ellis Podcast on February 12, 2014, he stated that he was never attached to the project as a screenwriter or a director, merely a consultant, claiming that the material seemed too tricky for him to properly render on screen
