Saw write-ups about this film, and they were mostly right.
We do see more of the back of the carpenters head than the front. There is limited conversation..the overall feel of the film is dour.
However,
I enjoyed it..the story is gripping enough and the two main actors are impressive.
The tension throughout the film is palpable but there is no histrionic acting and no musical score to telegraph what you should feel. The story is strong and is revealed bit by bit, adding to the rising tension.
The film is largely shot with hand-held cameras following the main character, Olivier played by Olivier Gourmet. The world is seen not from the point of view of Olivier but us as stalker looking over his shoulder and observing every move and facial tic. This gives the film an air of intimacy verging on voyeurism. Most of the film is shot in this way so that, at times, it becomes rather claustrophobic and one longs for wider shots to put the world of Olivier in perspective.
Olivier Gourmet won the 2002 best actor award at Cannes and deservedly so. It is a performance of slow burning intensity, always on the verge of boiling over but the lid is firmly on.
