Corridor, directed by Johan Lundborg and Johan Storm (Sweden), is a darkly humorous suspense-thriller, the likes of which would make Hitchcock proud. Frank (Emil Johnsen), a socially withdrawn medical student, goes about his daily routine with as little contact with people as he can manage - such as declining the invitations made by a classmate to study together and avoiding the other residents in his apartment building.
Frank is reluctantly roped into helping Lotte (Ylva Gallon), his persistently friendly (and moochy) upstairs neighbor with increasing frequency, much to his frustration. In spite of this, an uneasy friendship forms between the two after Frank notices signs of domestic abuse between Lotte and her boyfriend Micke (Peter Stormare, who is always awesome) and as things progress, they get increasingly more complicated.
Because much of the action takes place out of sight, Frank makes assumptions based on what can be overheard from his downstairs apartment and his conclusions and actions set up a chain of events that topple into calamity.
I was reminded a bit of Rear Window while watching it, though Frank – unlike Jimmy Stewarts’ proactive voyeur – desperately tries to avoid social interaction and involvement with the people living in his building. The use of sound in the film is hugely important, as Frank’s perception of Lotte’s relationship with Micke is informed almost entirely by what he overhears from his flat.
