In Sweden this and another two films of the first season premiered in theaters: Innan frosten (2005) and Hemligheten (2006). The rest of the season was released straight to video; only later was it shown on TV.
Two scenes remind of other movies:
First: Rear Window 1954 (Hitchcock). Kurt is watching his neighbors on the other side of the street. He sees short episodes of their daily life, just like James Stewart, and one dark window is contributing to solve the mystery.
Second: The Silence of the Lambs 1991 (Jonathan Demme). Linda walks around with a gun chasing/chased by the culprit unable to see him just like Clarisse Starling did.
