What
is instant arousal, why it’s important and it’s risks:
Instant arousal in filming is a technique
where the opening sequence or the beginning five minutes hastily takes the
attention of the audience. One reason instant arousal is important is because
instant arousal when done successfully almost insures the audiences full
attention for the rest of the film. However a risk of using instant arousal is
that if you rush the attraction of the audience, the audience will begin to
question whether the rest of the film will be as interesting as the initial 5
minutes. Furthermore if the opening sequence is full of intrigue unlike the
rest of the film then this ends up setting the bar to high resulting in the
disappointment of the audience.
What
is a classic opening and why does it work:
A classic opening is a conventional opening where the establishing shot is firstly the camera pans up a building from the ground, up past a window or a few then into an office showing the protagonist(s) of the film. That is one way of opening a film, another would be like shining where the camera follows the car giving the audience a feeling of mystery; this links to the film technique of slowly seducing your audience instead of instant arousal.

The Film noir trick is when the ending of
the film or a part of the ending is made to feature in or become the opening
sequence of the film. This trick is used make the audience think that nothing
is as it seems, also to give them a taste of what is to come and intrigue them
further. A lot of the time there are small details the audience most likely
won’t notice until they view it a second time. This trick is great because it
makes the audience feel that they don’t know nearly enough yet but at the same
time not to little. This is effective for reason that it allows the audience to
make initial judgements about the film, then making them want to see more of
the film. Directors say that this brings the audience onto their wavelength.
