Science-Fiction:

This teaser trailer for 'Elysium' begins by showing the logo of the film studio 'TriStar' pictures which is a successful company and people will be interested as they know that the film is like to have a big budget.

There is an establishing shot used which is from a birds-eye view and shows one of the locations (presumably the main one) in the film. The scenery shown is very bright and clean looking, the grass and trees are a vibrant green connoting life and purity.  It then cuts to another location however the two are juxtaposed, as the second is very dull looking and is crowded with people. The text on the screen shows that the film is set in the year 2154. It also states that only the privileged people live on 'Elysium' (the first location) and that it contains no poverty, war or sickness. The definition of Elysium is a place or state of perfect happiness, which is everything this planet is supposed to be. The second location is revealed to be Earth and is where the rest of the human population live. The lead character, Matt Damon states that he is going break into Elysium in order to save the rest of mankind.

The factors that make this trailer conform to its genre of Sci-Fi are:

The concept-this is because it is set in the future and is an idea that has never been explored.

Science Fiction films are usually set in the future, this one is set in the year 2154. They also are often set in space or on a different planet, this film is set on both earth and the planet Elysium. They also contain technologies of the future, in the trailer it shows a lady being scanned and cured of cancer.
