Christopher Nolan's film The Dark Knight is a great example of a thriller of moral confrontation. The use of enigma and action coding is a very important aspect of this film's success. Joker's entire being is basically enigma, you are always questioning what he is going to do next which is what makes him such an interesting antagonist. The mise en scene in this film varies and plays on the binary opposites, we see glamorous pent house parties, which have very high key lighting and have very expensive looking chandeliers and props, highlighting the protagonist's wealth. We also see backstreet pubs, where the lighting is very low key and the area is littered with waste and pint glasses, this highlights the antagonist's lack of funds, highlighting the binary opposites in the film. What I found intriguing about the Binary opposites was the way they were portrayed. In many films the protagonist is a struggling character, who is in need of money. In The Dark Knight the antagonist is the poor citizen, the Protagonist is a successful business man. The sound in the film is important, the subtlety of the sound in some scenes is ingenious, for example in the famous scene "i'm gonna make this pencil disappear" there is an eerie silence engulfing the room as joker speaks, until finally he slams one of the guards heads down, shattering this silence.
The Dark Knight
This is an example of the antagonist and protagonist's psychological disturbance.
Enigma Codes
The Dark Knight has enigma codes flowing throughout. The antagonist (Joker) has a lot of scenes where enigma codes are used. In one scene he is firing a gun randomly while the protagonist rides towards him. He keeps saying "I want you to hit me", throughout this scene the audience are wondering if the protagonist will hit and kill the joker, thus breaking the protagonist one rule of never killing.
