In 2014, writer/director Éric Falardeau explained how he developed the idea and script for the film. "A few years ago, me and my ex-girlfriend were talking and making jokes about someone rotting from the inside. At the same time I was working over my master thesis about body fluids in gore and porn films. Little did I know that our small talk would merge with my studies. I then started putting ideas on paper and working on the script on an irregular basis (between my thesis, my day job and another film). The script became more and more personal, like a reflection of my inner self and my readings at that time of my life."
