As I discussed earlier, a thriller aims to thrill the audience. This is done by employing a well known set of conventions, mainly these are:-
- Male protagonist - usually very macho or highly intelligent, or sometimes both.
- Female or Child is the vulnerable victim who needs to be saved by the hero.
- Antagonist usually on a par with the protagonist (can match their strength, can play mental mind games, etc). Also, unlike other action based film genres (i.e. Horrors), the antagonist in a thriller is often known to the audience and/or protagonist straight from the outset. And the antagonist often will engage in some sort of communication with the protagonist as well, e.g. telling them riddles through a phone call, etc.
- Fast editing and camerawork
- Plot revolves around a crime, mystery, etc.
- Protagonist does NOT always defeat the antagonist, or at least not without some sort of sacrifice.
- Fast tempo non-diegetic music.
- Emphasis on some diegetic sounds, e.g. the ticking of a clock which is counting down the time for a bomb to explode.
