Previously on August 15, I-LAND canceled all schedules when a cleaning staff was tested positive with COVID-19. Since then, all cast and staff members have been tested and went into self-isolation. Also, the filming site has been disinfected. But on the afternoon of August 17, a media outlet reported that I-LAND resumed some recordings at the Paju filming site after most of the production team and cast were tested negative of the virus. Some staff members are on standby for the results and continue their self-isolation until then. Those who have been confirmed have returned to their schedules, and I-LAND started to normalize the filming in two days. Source (1)
