Shot in 18 days.
Directors Kevin Kölsch and Dennis Widmyer were initially going to go with a traditional orchestral score until composer Jonathan Snipes convinced them to let him do a synthesizer score instead and considered his ideas for a synth score they knew it was the only option. "If you just listen to the soundtrack on its own you can hear the journey that Sarah goes through."
An audience member passed out during the climax of the film at the New York premiere. The projectionist had to stop the film and turn on the lights as the audience member was escorted out. The movie was then rewound two minutes and started up again.
Production was denied shooting permission at a Los Angeles bar once the script was read and the material deemed "too evil."
The film started as a Kickstarter project and was aided by the support of author Chuck Palahniuk's ('Fight Club') fans. 100 donors to the project had their names thanked in Chuck's 2014 novel 'Beautiful You.' Co-writer/co-director Dennis Widmyer runs Chuck's official website and manages his social media.
