Purpose - The purpose of this trailer is to advertise the film and actors and company to the public and viewers. There is also they purpose of matching the trailer towards the film, so if the film is going to try and scare the audience if it is a horror then the trailer has to have the same effect to make the audience want to go see the film. So in the case the trailer has to be scary and chilling without revealing any important bits of the story.
form - The form of this audio visual promo is a film trailer. This form is used to show small parts of the film that the audience will be interested in and put them together to advertise the film. it is also used to advertise the produces and companies behind the film and to give the target audience an idea about the story line of the film.
content - The content of this trailer and tell the audience what the film is about. It does this with a use of editing and setting etc. The setting in this trailer tells us that the story is set in america and could start of in a school. It also keeps the audience interested because at the start of the trailer they rush inside from the rain but it could be from anything, a storm or monster or invasion just like other films. This keeps a bit of mystery to the story and in turn keeps the audience interested.
meaning - Looking at the trailer i can see meaning behind the directors choice of shots and mise en scene for example the first bit of the trailer is set in a school with plenty of people to be in danger instead of just a couple of people in a house somewhere. Some of the shots in the trailer have been done for a reason because they are shaky and unstable but i think this is to make it look like you are part of the film and can see from someones eyes that are there. part of the trailer has a teacher guiding students through the hall and its a mid shot teaching tracking him from behind and it looks like you are a student following him.
genre - the genre of this film is more than action thriller instead of horror thrillers like some of the other trailers I have analysed. Whilst some thrillers have fictional things in to scare the audience this is a different sort of genre were the story is based on fact instead of fictional things. I think that this can have a different effect on the audience because they viewers can realise that that could actually happen which can come across scarier than fictional thrillers.
audience - the audience for this film will be people that are interested in films with other natural disasters in such as 2012 or Pompeii. Also the film is rated PG-13 so anyone younger is either not aloud to see it or wouldn't be bothered about it. I think that it is more of a teenager/ adult film because i don't think that child would have an interest in films about the weather compared to films about super heros.
