Treatment

Our opening will be based around the stereotypically used idea in slasher films, that is a group of young people enter an ominous location (old train tunnel in this case) and they encounter something out of the ordinary (train whistle) and one member (in this case the "jock") goes of in search of the source, and the others later discover his body and also encounter the killer and it turns into a pursuit in which they all inevitably perish as well.

This should make the audience feel terror, terror at the horror faced by the characters and terror for the scenario, the killer's Mise En Scene will also cause terror to the audience as he will look intimidating and merciless (will go into greater detail on prop post).
The opening will also make the audience feel empathy, empathy for the hopelessness of the situation and sorrow for the unfortunate events occurring to these young people.

The narrative will have to sound natural, as if it was an ordinary conversation between three young people, this can range from talking about celebrities, news of the time and currant life events, while taking into account that some things may seem offensive to certain audiences.
The narrative could also be related to anecdotes from the characters, something that gives the audience an idea about their personalities, maybe even to give the audience an emotional attachment to the character that further increases their shock when they are murdered.
The dialogue will always be diagetic as the camera will track the characters.

We will be featuring 4 characters, a group of 3 young teenagers comprising of the stereotypical casting in a slasher film; a jock (a physically fit sporty man, over confident and often arrogant), a "geek" (a skinny physically weak, intellectual character, who would be the first to suspect danger and will be over analytical of the situation much to the annoyance of the jock) and lastly the "Drama queen" (a young girl who often exaggerates the situation and is the most potent to being easily scared, will scream often and will rely on the prowess of others for protection).
And of course the killer, the entire film will revolve around this character so it would be wise not to release too much information about him in the opening and to leave the audience in suspense to his identity as is commonly done in Slasher films.
The killers role will be to create the feeling of threat for the audience and move the plot forward, the killer will the be main variable that keeps the film going.

The film is set firstly in a open country field environment, in which we will do an establishing shot of the area, and introduce the characters, and then for a certain circumstance they are forcing to walk down a dark, long, over grown train tunnel (pictured in location post).

The lighting of the scene will have to be dimmed at certain points during filming, and a filter may be used to dim the scene in order to create a gloomy atmosphere, despite the colourful Mise En Scene of the characters, they should appear more grey and hopeless to create tension.

We want to use the camera to emphasise the panic of the event, as the plot escalates the camera angles will change more quickly, this is to exaggerate the panic and confusion and increase tension for the audience, this also highlights the emotions shown by the actors.

Editing will be used to combine all the different camera angle shots into one sequence that will seem very fast pace and to give the audience a better view of the Mise En Scene of the surroundings and scenery, for this Shot Reverse Shot will be crucial to set the scene and add the feeling of panic, along with an added incidental non diagetic sound track.
