Teaser trailer for Norwegian horror Fritt Vilt 2

The sound of a heartbeat is used in time with the fade out to black to create a montage of action which builds suspense. As soon as we see someone run past the protagonist (element of fear) loud music starts to accompany a montage of action. The name of the film is shown at the end, then there's one last extract from the film before the release date is shown. This is effective as the use of the last extract is quick and illustrates the characters fear, which makes the audience want to see what she's scared of.
