Through creating a Twitter account and posting regular updates, Dark Horse Productions was able to effectively promote its new film. This included uploading a trailer and the first two minutes of footage. Using social media allowed the company to reach a larger, global audience. The teaser trailer for the film was only 21 seconds long but conveyed the dark atmosphere through brief clips and left audiences wanting more information. This increased anticipation and views for the film online. The film's unique selling point is its focus on the psychological characterization of the troubled characters, including a religious subplot, rather than solely focusing on crime elements like many similar thrillers.
