Panic Room- Trailer Research 2

Panic Room is a 2002 American thriller film, in which a woman (Meg) and her diabetic daughter (Sarah) purchase a new house. They are shown that this house has a secret room that is impossible to get in once closed. The room has supplies in order to survive, cameras to see around the house and a phone in order to contact the police. 3 men break into the house, one an employee of the residence security company and one a grandson of the previous owner and try to steal millions worth of bearer bonds which are locked inside a safe in the panic room floor. Eventually they are all either killed or captured by a SWAT team.
The music at the start is slow and soft, like it should be played from a childrens music box. This is typically used in thriller movies as it creates and effect of innocence, juxtaposing what is going to happen in the rest of the movie. The editing at the beginning is slow, with many long fades to black, as it supports many of the establishing shots seen in setting up the narrative and putting the rest of the trailer/film into context. The mise en scene at the start is typical of the thriller genre as there aren't many colours with blacks and greys most common in the trailer. However the lighting at the beginning is high key showing again that the beginning isn't supposed to be tense.
When the estate agent reveals the safe room, the atmosphere changes with the music stopping and being replaced with more speech from the film and deep rumbling sounds and screechy sounds which increase the tension. There is also pauses in the audio which gives the time for the audience to take in what they have seen so far and builds suspension which is supported by diegetic sounds such as footsteps approaching. As the trailer progresses, there are more close ups and tracking shots which show the panic the characters are in and that they are trying to escape danger. The editing also increases with quicker cuts speeding up the trailer, and when there are fades to black diegetic speech can be heard with no other distraction, focussing on the woman's feelings and the audience empathise with her. The mise en scene is similar all the way through, excluding the lighting which progressively gets more low key throughout, reflecting the dark feelings, situations and atmosphere. The trailer ends with the little girl saying "What is he doing", which represents the audience's feelings and the mother replying with, "They're locking us in". That last sentence creates suspense and panic for the audience as they only hear her say that with no visual clues to what is happening. It will make them want to go and see the film.
