District 9 question

Most texts today mix genres. How is this true of District 9?

In the film District 9, the first few scenes are filmed in a documentary style, there are close up shots of people being interviewed and the shots are recorded in a handheld style. There are also clips where the film is shot in the style of a news report, there are tracking shots following people on the ground from the view of a helicopter. These styles of filming combined make the film seem realistic and show elements of a documentary genre.

In the scene where they are in the hospital, there are conventions from both the sci-fi genre and the horror genre. There is a close up of Wikus' arm after he has started to go through his transformation. Transformation is a common convention of sci-fi and this is combined with the use of  CGI to make his arm look like an alien. This convention is common and can also be seen in films such as The Fly when he transforms in to a fly, he undergoes transformation from a human and starts to see changes in his appearance that are constructed using CGI.

When people are shot in the film, there are conventions of realism, horror and sci-fi. An example of this is in the scene where the alien is told to stand by the wall and is shot. The alien is shot using a futuristic alien weapon, alien technology and weapons are a convention from the sci-fi genre.
