John Klute (Donald Sutherland) is a private detective hired to find a missing man, presumed dead. Bree Daniel (Jane Fonda in an Oscar winning role) is a prostitute who was receiving obscene letters from the man. Klute and Brie team up to tackle the case of the missing man.
This is just something I randomly watched off of Netflix, but I'm certainly glad that I did. This movie is masterfully directed, making great use of shadowing. Fonda and Sutherland are both excellent. This movie is a must see for fans of mysteries or film noirs (although it's not really a noir, it's definitely in that vien).

8/10
