Frozen

The trailer starts with three friends, to male and one female who are the main characters throughout the trailer. They are 3 good friends as the two male characters have a laugh with one another, they seem to be enjoying the snow slopes and skiing At the start of the trailer you have the main female character talking to a male character of which she is trying to get her male friends on the chairlifts. Within this shot you have a shot of the two characters talking with a machine in front of the shot which seems to be moving. This signifiers the audience that something bad is going to happen, with the machine not in focus it may also signify to the audience that the characters in the trailer are not oblivious to it. Diegetic sounds of machines turning also signifies to the audience that something bad is going to happen.

Within the trailer you have cuts to the titles between a couple of clips, the titles of the trailer have an effect of snow around it which gives the impression to the audience that the environment is cold, this may also give the audience an idea of what the mood of the characters will be like because of the environment they are in.

Between each clip you have titles which seem to cut fast to the titles and then back to the clip again giving it a fast pace to the trailer, this may connote the audience that the situation will happen fast. 

The titles between each clip throughout the trailer gives you a documentary style as few of the titles such as 'with over 30 million skiers and snowboarders in the US' and also 'over 5,000 chairlifts in operation' These titles are giving you facts throughout the trailer of which gives you an impression that the trailer is filmed in a documentary style.

The setting of the trailer is what you would find in thrillers and horror, the setting in the trailer involves a derelict place which connotes to the audience that they may soon need help of which is not there because of them being high up in the chair lifts.
