Under Suspicion is a total mind fuck of an investigation. The story and intrigue are powerful, and extremely well choreographed. It's so twisted and tight, with the right score, a good photography, and smooth editing, that by end you get to hate just about every character.
Morgan Freeman, Gene Hackman, Thomas Jane, and Monica Bellucci are just perfect for their role, playing their assigned persona just right and on the edge.
It's not for everybody, since its a harsh subject matter and no psychological punches are pulled as Hackman's character is harassed. Also beware, very little happen in this film, the game is all mental.
I highly recommend it for the maddening asinine trip you'll get on.
