Thriller Mood Board

The images above represent the thriller genre. Thrillers play on the audiences minds, without showing blood, gore and how a murder actually happens, they let the audience visualise it in their heads.
The image of the eye and the woman sitting beside the mirror show paranoia and almost madness, although there isn't anything gruesome about them, it still sends a shiver down the spine of whoever's watching the film.
Se7en was a very successful thriller movie, and recently, Inception (2010) was a successful thriller.

Horror Mood Board

This mood board represents the horror genre. Horror reveals more gore and gruesome details, it almost makes the viewer cringe at the detail it shows.

The devil represents death and hell, a major component in the horror genre, alongside the devil, the grim reaper also represents death.
Some very successful horror movies are Halloween and Frankenstein.
