What is a Thriller?

We have been learning about the film genre 'Thriller'.  we looked into the film 'The Usual Suspects' we learned that a thriller consited of many types of media, such as 'Mystery 'Unexpecting Endings 'A Clever Storyline' 'Death' 'Crime solving'. with the 'Usual Suspects' we analised the poster for the film. we analysed from that who is the most important person in the film. so overall a thriller is a film that is full of mystery and death with a twisting storyline. In a thriller music and lighting and the mise-en-scene are a major part of making the thriller. The music helps to build tension.
