How does the "Donnie Darko" film cover reveal it's a thriller?

Donnie Darko is portrayed as a thriller, by looking at the cover. We can tell this because of the colours, font, facial expressions, signifier and conventions.
The front cover is assembled by using colours such as blue and black, the character Donnie is presented as blue this gives us an impression that the film contains ambiguity.
The colour blue also could lead us to infer that time travel is entered into scenes the colour blue is characterize as a negative colour which my give a clue that this may be a gloomy film to indicate death.

The brightness of Donnie on the front cover could also give out a signifier of space and time travel. Because he has been portrayed as the main character. So the light shows his importance, and to the world. This is because light is a very heroic symbol so it infers he may be a hero.
The darkness of the film cover (black) which are losing in from each corner  revealed that the world maybe ending by getting this impression the audience could jump to the conclusion that Donnie is a hero because he is a saviour of the earth.
The props in the front cover is a item such as a axe to illustrate his destruction it gives the sense of danger and danger is a convention which is how we can determine this is a thriller.
The centre  of the body shows a bright beam (orb) this could infer he is being controlled and is under influence.

Another connotation is his facial expression these give off a negative vibe as it creates a sense of evil and deviousness, we know this by his eyes because they show that they are off concentration as if he is thinking of something. Which gives clearer thoughts towards the axe.
The last piece of information reveal it is a thriller film is the lettering and font, the main title  "Donnie Darko" is bold and is shadowy to infer mystery this provides conventions for being a thriller. 
The tag line shows it is a conventions of a thriller as it is a question " WHY ARE YOU WEARING THAT STUPID MAN SUIT" the words language comes across as angry and sarcastic as Frank say this back to him when he said " why are you wearing that stupid man suit".
