Starting the first day of the year by going through my dvr and watching films that have been sitting there too long. This is a well-made suspense thriller about a wife of a British businessman who begins to receive phone calls from someone threatening to kill her but she is unable to prove it. A bit slow paced but it's stylish and does a great job with the mystery element of the story. The stalker has such a creepy high-pitched voice that feels so unreal, there are enough red herrings to keep you guessing, and I had fun trying to solve the mystery. Great performances all around.
