Conventions of a Thriller Film

There are many conventions of a Thriller.
One of these conventions is that they appear on a grand scheme.  The stories in which these films are set, (often including a 'based on a true story' at the beginning), have bigger plots buried within smaller plots, and some even have the solution to the problem within the film (such as maybe the best friend being the villain) right there before our eyes, but we wouldn't notice because the story is woven so tightly that we don't expect anything we shouldn't.
 Another convention of these types of films are the odds against the protagonist. Most thrillers have a protagonist and an antagonist, however the antagonist is shown to have a much greater variety of power, often shown by the fact the antagonist murders a whole bunch of people at once, or slowly picks off his victims; often being in control of an entire corporation or keeping the protagonist within mystery and fear where the antagonist wants them. This makes the audience want to know how the protagonist will overcome the odds in order to defeat the antagonist, and encourage them to continue watching and even recommending the film as another source of advertising.
Another convention of thrillers is a complex narrative structure. This can include red herrings, which are basically false scares, or maybe the protagonist discovers something about something or someone that the antagonist wanted them to find to make them think a certain way and be quite misleading, which can either engage the viewer even more than before, or confuse them beyond belief. This kind of technique can be used in thrillers to set the boundaries of trust between certain characters.
 Finally, a convention of thrillers are the themes of identity, mirroring and voyeurism. These themes are often used to keep something hidden, such as an identity: maybe keeping the identity of the antagonist a secret or keeping certain traits of a character in mystery for the audience to figure out.   Mirroring can be used for suspense and unease at times, and are mainly used in horror thrillers to be quite mysterious, but can also be used in thriller films to create more of an atmosphere, which is vital in thrillers to give off a certain feeling that the director wants you to feel. Voyeurism is often associated with spy thrillers as sexual content is often associated with rich spies, and sets the tone of happiness. However, in recent films like Skyfall, the woman involved in sexual content with James Bond/Daniel Craig was killed off in the very next scene, so not only was her character a write-off most didn't expect but it turns the film around a little, because a possible main character was killed off, paving the way for more plot twists and more hatred for the antagonist.

I never did like what they did to the Aston Martin in that movie...
