Adam Young underwent some thorough research on the various forms of amnesia and dissociative identity disorders whilst he wrote the script, to give the story as much reality as possible and even consulted psychology professors by letting them read script drafts and offer their insight and professional opinions regarding the character of Richard Smith.
Despite pitching and applying for funding, Adam Young was denied a budget by his university during his final year as he was making the film as a dissertation piece, and the project was therefore self-funded as he shot scenes between his work shifts and university assignments. The ambitious project exhausted him and has since been handling smaller films with less actors, locations and visual demands such as visual effects. However, Young believes this film was the ultimate learning curve for his film-making and was instrumental in developing an extremely positive reputation for his abilities amongst local film-makers.
Much to his disappointment, Adam Young regards this film as unfinished - as there was a final scene between Richard Smith and the Interviewer, which involved Richard attacking the Interviewer and being restrained by doctors. The scene was supposed to give away the sole purpose of the interview process, but due to one of the extras not attending the shoot and no available time to reschedule, Young had no choice but to skip the scene and continue without it.
Ben Ridley composed the music without seeing a shot of footage. Being away in Australia at the time, Ridley wrote, performed and recorded the music within a few days, simply working from the script that Adam Young had sent him.
Aside from Adam Young, none of the crew had any training or experience in film-making and were friends of Young's who agreed to assist him in getting the film made.
