We can tell by the film Birck, by Johnson is a thriller film within the opening two mitues by the conventions of a thriller film used. One of the main things that we see in every opening sequence of a thriller film is the use of close ups. We see loads of close ups because they want us, the audience, to be asking questions about what is going on. By showing us loads of close ups, they are hiding crucial information from us. This is one technique that all thriller films use.
In this film it made us ask questions such as:-How does the girl die?
-Why are they there?
-Who is the boy to the girl?
Another convention used to show to us that this film is a thriller is through the eerie music being played. It sounds like a stringy guitar being played as if it was a western film.

In the opening sequence like any other typical thriller film, it makes us ask questions. The main question that I would ask is why is she getting cold down in the basement? Isit generally cold or is something in the room making her cold? Also, the use of sound makes me ask questions. The sound of they keys rattling and the sound of some one walking on broken glass would freak anybody out when you do not see any other presense in the room. So the question that I would ask about that is where are them noises coming from?
At the start of the programme we see a quick sharp shot of darkness. A blank screen. Just by the producers doing this, it makes us feel uneasy as we can not see what is going on but we could hear sound coming from the screen. On the screen at this time we hear rattling noises as if some one is trapped in, this makes us feel unsure and nervous. You can tell that I was unsure because when we saw the action, it was a helicopter flying over the sea. The sounds that I was hearing was the wind blowing in the background making a impact noise and then it comes to a stand still when we see the girls.
