An artfully composed mix of crime mystery, erotic melodrama, police procedural and courtroom drama, his compact 75-minute movie is upfront about nudity but very teasing when it comes to revealing its plot.
Mathieu’s own character is almost as clueless as the viewer. A married provincial businessman caught up in a passionate affair with the wife (played by Mathieu’s co-writer, Stéphanie Cléau) of the local pharmacist, he finds himself entangled in a murder investigation. Is he guilty? Innocent? Both?
As whodunits go, The Blue Room is wilfully frustrating. But as the story flashes back and forth between a judicial interrogation and the events leading up to it – which includes torrid liaisons in the hotel room of the title – the glimpses we get of the protagonists’ complicated desires and flaws keep us enthralled.
Certificate 15. Runtime 75 mins. Director Mathieu Amalric
