Before the release of the film, the owner of the asylum filed a lawsuit against the film being shown in theaters, claiming that the film will have negative effects on the sale of the building. However, a Seoul court in late March 2018 ruled in favor of the film being shown. On 28 May 2018 Gonjiam Psychiatric Hospital was demolished.

Although the asylum certainly had a grim past, it was primarily abandoned due to economic downturns, unsanitary conditions, and problems with the sewage disposal system. Debunking the paranormal stories didn’t prevent tourists, ghost hunters, and filmmakers from visiting the facility.
