Narrative in Trailers

Which trailers do not give you a great deal of information about the narrative? What do they convey and what elements are needed to do this?

Percy Jackson and the Olympians does not give much information about the narrative of the film but it does convey that the film may be centred on the young teen who is the main focus of the trailer. This implies that he is Percy Jackson.

The elements used to show this is the camera action following him and he is on his own which makes the audience watch him only. There is also a sense of mystery as to who he is at the beginning of the trailer which further focuses the viewer’s interest in the character.
