In one scene at T-Centralens subway station where the film crew didn't have permission to shoot, the extras where set loose with the ordinary people. In that scene Jannika (Tove Appelqvist) sets a policewoman's hair on fire. The subway station's security people, that didn't know it was a movie production, arrested three of the extras, which they thought were real alcoholics and drug dealers.
This was the first time that DoP Jens Fischer worked with the Super-35 anamorphic process for the 2,35:1 AR.
