Examples of the Enigma Code:
- The majority of the opening sequence is shot from the killer's Point of View so we don't know who he is or what he looks like.
- This opening does not really establish the context of the film or setting, the audience only gathers that it's set in England because of the dialogue.
- The motive for killing the prostitute is not known by the audience at the beginning of the film (although we find out later on).
- The physical location is very dark so it remains a mystery where exactly this is and what else is in the location.
Examples of the Action Code:
- Man starts filming with a camera in his jacket.
- Man approaches prostitute who offers him her services.
- She leads him down a dark alley and into a building.
- They go up a flight of stares and into a bedroom.
- He takes out a (unseen) weapon and approaches her.
- She screams and he continues to film her reaction.
