The logo for the film's production company Morgan Creek Productions is also used, it consists of a still image and moving text. This only appears onscreen for a short amount of time, perhaps this is because this is not a well-known production company, and therefor its logo cannot be used to draw in an audience.
Titles, a form of written text are also used, to help the audience make sense of the narrative. It also helps to create a sense of anticipation surrounding the films storyline.
Audio from 'Dream House' Trailer: The music is soft and played on a piano, this creates an eerie atmosphere, and sets the scene for a horror film. The voiceover gives the audience background information about the film, helping them to understand the narrative.
