The Thriller, as a film genre, is an enduring one with broad audience appeal and equally consistent with critical acclaim and mass audience. Yet it is also a genre of cinematic narrative that lacks the hard specificity of tangible edges and conventions of other genres such as SciFi, Horror and RomCom. It’s a genre that can be all too easily misunderstood and mis-construed particularly in the context of transmedia and multi-platform experiences.
What is it to be Thrilled…? What narrative concepts do we need to deploy to satisfy that contract with the audience?

Certainly there is much written about the nature of Suspense which is at the heart of generating Thrills beyond the raw kinetics of the action sequence.
Noel Carroll cuts to core with the notion that…
“We experience suspense by entertaining uncertainty regarding an unfolding event which has two logically opposed possible outcomes one moral the other immoral of which the moral outcome appears improbable and the immoral outcome appears probable.”
And A. R. Duckworth contests and expands on Carrol in a lengthy series called The paradox of Suspense
However such compelling and conceptual understandings of Suspense and the Thriller need also to be grounded in hard narrative, scripting and creative development choices. And this is where I see two core principles of The Thriller that stem from the generation of rich Thriller Storyworlds.
1. FORBIDDEN KNOWLEDGE
At the heart of the Suspense Storyworld is Forbidden knowledge. Such knowledge is secret, protected and has the power to do great damage. It is knowledge characters are Not allowed to know. So, invariably, storylines and plots will happen when that secret, dangerous, protected knowledge leaks out, when it becomes known by people who shouldn’t be allowed to know, often people who don’t want to know and may, ultimately, wish they never knew..!
This observation of Forbidden Knowledge in a suspense story is obvious in all manner of Suspense films; notably, of course, in those of Hitchcock. Most often it’s a singular event - a crime, a murder, a corruption - which is witnessed by someone who cannot be allowed to know. At other times characters are compelled to pursue the Knowledge to discover what it is, unaware at first of its Forbidden nature. A third archetypal variation sees a character encounter the forbidden knowledge but be unaware what the knowledge is or what it means and must unravel the mystery to escape. A film like North by North West plays out in this way where the mistaken identity of the protagonist brings him into contact with the Forbidden knowledge yet the character himself does not know what that knowledge is.

In any of these variations it is the value of the Forbidden Knowledge that compels the character forward and into dramatic action. In the case of the much bigger canvas of the Storyworld which may underpin multi-platform and long-form thriller narratives, the articulation of exactly what the forbidden knowledge is, along with its value and power, is what will serve as a prime motivating force that is sustainable.
What the Storyworld writer must carefully map out is the scale, scope and ramifications of the forbidden knowledge - how big is it, how far does it spread and how much fall-out could come from the Knowledge being unleashed. (corruption, murder, conspiracy, secrets, lies) This forbidden knowledge is a central, unshakable truth of the Storyworld. Any character (or indeed audience-member participant) who comes in contract with the Forbidden Knowledge will be changed and compelled into action - they will no longer see themselves or their world the same way.
Think of your Forbidden Knowledge as Secrets and Lies - very big and important Secrets and Lies. The secret needs to have dire ramifications if it gets out, and the lies are what are told to keep the secret a secret. If you can articulate a big set of secrets and lies at the heart of your suspense Storyworld, then you will have the fuel to make that suspense propel stories, characters and audiences across episodes and platforms.
2. TWO WORLDS
The second crucial element in the Suspense Storyworld is the concept of ‘Two Worlds’. The effect of having a clearly articulated and compelling Forbidden Knowledge at the centre of your storyworld design is that you effectively create Two Worlds. One is the world outside the Forbidden Knowledge, where the secret is maintained and the characters are ignorant of the secrets and lies. The other world is the world inside the Forbidden knowledge, this is the world the characters will encounter and move into once they have transgressed and come in contact with the forbidden knowledge.
This conceptual construct of the Two Worlds is vitally important for sustainable suspense drama - particularly in a transmedia, long-form or episodic environment. In a traditional feature film narrative structure this duality would simply be the shift for a character from their Status Quo into the inciting incident that casts them into adventure. So in the example of the North by North West, the first world is the status quo for Thornhill staying in the hotel. The shift into the ‘other’ world comes when he is mistaken for another man, George Kaplan, and becomes caught up in the spy world of stolen microfilm.
But in a Storyworld with a much broader scope than a feature film, we need to be much more complex in designing our two worlds as potentially our world will see numerous characters and audiences take various paths between the two worlds. Each of the two worlds, inside and outside, the forbidden knowledge, will have different Storyworld rules. For a character outside of the forbidden knowledge, the world will have certain expectations, behaviours and rules of normalcy. However once a character crosses over into the other world by coming in contact with the forbidden knowledge, hierarchies, behaviours and what is ‘normal’ will change radically.
These two principles - Forbidden Knowledge and Two-Worlds - are part of an approach that importantly puts the development of World first before articulation of Plot. Design and develop a powerful and dangerous ‘Forbidden Knowledge’ and then shape ‘Two-Worlds’ that are bridged by that knowledge. The more radically separate the two worlds and the bigger and more powerful the secret knowledge, the more explosive potential your suspense Storyworld will be. Characters and plots, circumstances and events, will naturally flow from such pressurised Storyworld dynamics. But if you begin with character and plot you run the risk of such characters at play in Storyworld that is not sustainable; one that quickly runs out of fuel as it tries to support ongoing, multiple or interactive dramatic experiences.
