Target Audience

The target audience of a thriller movie is not always the same; the target audience depends on the sub-genre of the film, and the topics it covers.
Films such as 'No Country For Old Men', which was rated R, have a target audience of young males. The action and violence contained within films like these appeals to the male viewers. Moreover, the viewers are generally young as they enjoy the fast-paced nature of the films.
Thrillers that can also be classified as horror films appeal to females more than males. This is because horror films target young women, therefore, thrillers that are also horrors would share some of the same conventions as the horror films.
Political thrillers, such as 'The Manchurian Candidate' and crime thrillers such as 'Se7en' are intended for the older generation - these films are slightly slower in pace, and require more logic to understand.

Our thriller would be quite psychological, and would therefore be aimed at young women. With this in mind, we would cast a female as our main character - this would make it easier for the audience to relate to the character.
