From the trailer alone we see scenes of quick cuts, tense music and a high sense of mystery, all of which are main conventions of a thriller.
One of the films most notable scenes is the car chase scene embedded below.

In this scene we see characters 'Martin and Gina' trying to escape a enemy that is seemingly trying to kill them. It is clear this scene is action packed as it has over 120 cuts within those two minutes. The non diegetic chords played by the orchestra suggests trouble is a clear presence in this scene. Also the mise en scene further makes the scene more exciting, thrilling and dangerous.
