Slither

In  the trailer a lot of low key lighting was used when he was digging out the meat and walking through the forest with plastic bags, it added mystery as to what was in the bags that he was carrying. Low angle was used at 0.16 to show his positive emotion towards the amount of meat he was seeing. Wide shot was used to show the variety of meat and allowed the audience to see that he was after a lot of meat which was more than any human could be capable of consuming. 

In the first image a lot of special effects and makeup have been used to show his transformation from a human into this monster. His face looks very fleshy and its easy to see that he's not the same person that he was at the start of the video. It's a medium close up shot to show the extent of his facial disfigurement.

In the second image its a high angle shot to show the slither creature making its way to her face. The woman seems relaxed and oblivious to the fact that something else is in the bath with her. The slither creature is red, the colour red connotes danger.

The poster for the film allows the audience to allow that the genre is horror. The title 'slither' is smudged and shows a slithering effect. A blood splatter behind the title signifies something bad will happen, blood most of the time suggests death. The title for slither looks like a similar font to 'SAW' which shows the genre. The creatures are the most prominent image on the poster which illustrates that those are the main things of the movie. There are several creatures which shows a mass of creatures that will affect people during the movie.
