Research: Conventions of Characters

Thrillers normally represent a type of background when being filmed. When creating a thriller, distributions try to make the film as relatable as possible to normal everyday life, even if it's a futuristic film, the characters still face general problems.

Characters can be based upon:

Psychological Problems

Terrorism

Convicts

Spies

Normal Working Life

Sports

Drug Addition

Social Problems

Assassinations

Adventuerer 

All these things are thought about when a distribution is about to create a film. They use these to create characters and how the character is going to be represented.
