The first couple of shots in this trailer show the type of people these characters are and show the relationship between them all; they're shown as family and close friends, this is important for the audience to know because it will change their view on how the characters react to different events and build a personality for them. The second shot shows the location as a middle class looking home which will help the audience relate to these certain people as most people go to the cinema to watch movies, having a group of people the audience can relate to will make them feel on edge once the film is over like the plot could really happen.
The transitions change 30 seconds in once the two young girls ask if they can play outside, this would make you suspect that something bad is about to happen to them because of this indication. A sound effect is also used just before this transition is shown, the loud band which then turns into the sound of a quick but gentle drum begins to play as a non diegetic sound.

The shots begin to slightly speed up at the point of discovering the two young girls are missing, pathetic fallacy is used 48 seconds into the trailer as the weather changes to rain when the parents are worried, this presents the change of mood to audience in a more obvious way. Using pathetic fallacy also sets the emotion for the scene which reflects back to the audience and effect the way they are seeing the situation as well.
The actors in the movie are unique selling points as Hugh Jackman and Jake Gyllenhaal are actors that are taken serious which makes them good for the roles they were given; Hugh Jackman is mainly famous for the very famous movie 'X-Men'. These two actors are working along side people such as Paul Dano whom is recognizable for films such as 'Little Miss Sunshine' making the audience that recognize these actors feel curious to if they did a good performance in this movie also.
Extreme close up shots and new characters are introduced as we realise something has gone wrong (the children are missing) this hints more of the plot and genre as a chrome/drama because one of the characters now in shot is called 'Detective Loci'. The close up shots are very effective because they create enigmas for the audience; the shot is so close up it is almost unclear to make out what is in frame. At this point the music also changes to something that would be used to build tension, the repetitive sound of echoed drums continues until a medium shot of Detective Loci is shown as he says to the parents of the missing children "Im going to find your daughter", to which then this use of dialogue and the change of setting and music creates excitement. By showing Loci say this to only one of the families signifies the roles that are going to impact the plot and events a lot more than any other characters.
By increasing the intensity of the music in the next shots allows the audience to figure out that more is about to happen, with the transitions changing back to fading to black and showing the same props that are shown at the beginning of the trailer before we meet Detective Loci just in a different way hints that this is something important in the film - the van that was once driving along the roads next to the families homes in broad day light just before the girls went missing, is now smashed against a tree at night time with Detectives searching it. The shots of this vehicle being shown in different lights connotes to the moments of the film and changes the emotions of it, the denotation of the darkness connotes uncertainty and mystery which links to the genre of the movie whereas the shot in day light comes across as a lot more realistic to the audience creating mundane realism, allowing the viewers to relate to the characters and setting.
From this point on the anger evolves around one character that comes across as very timid and insecure, an unrealistic expectation on someone that would abduct two young girls, although using someone with these characteristics makes you want to look more in depth on what actually happened to these children which means the audience would have more of a reason to go and see the film. The timidity of the suspected abductor - Alex, has very little dialogue in the trailer which doesn't give too much away about him, they use other characters to express he way Alex is, such as his mum, who says to Detective Loci "That boy has never been in trouble not a day in his life", this creates confusion for the audience as they are given mixed signs on who could be the main antagonist. Another man is shown as a negative character when Loci goes to his house and barges in to arrest him; we aren't told anything about this character, not even his name.
The music builds up more from 1 minute 23 as well as the diegetic sound to present the anger and fear of the characters, this music results in a medium shot of one the daughters dads in front of Alex holding a gun to him which again creates a more thrilling experience as the even the likeable characters that we see at the beginning of the trailer to be shown as violent. This subverts the stereotypes of the roles of protagonists and antagonists because the antagonist is usually stronger than the protagonist and isn't afraid to harm anyone but in this movie the suspected antagonist is shown as weak.
Showing the title of the film written on the paper that has continuously been shown through out the trailer using extreme close up shots creates a theme for the movie as the map like drawings can hint clues to what the whole plot could be about and why certain things happen.
