The beginning of the film pays homage to Terrifier, which starred Jenna Kanell and was directed by Damien Leone. Kanell stars in and co-wrote Faceless After Dark, and Damien Leone receives a special thanks at the end of the credits.
Faceless After Dark premiered at Fright Fest 2023 in London, UK, on their main IMAX screen, to an audience of over 730 people.
Jenna Kanell performed all of their own stunts in the film.
After the Fright Fest premiere, the Q&A moderator asked Jenna Kanell how much of the script was inspired by true events. Kanell responded, "I've never killed anyone."
All of the screenshots of social media DMs, including several subliminal single-frame "dick pics" that flash on screen, are all real messages and images received by star and co-writer Jenna Kanell.
