2. Editing.
Straight cuts are featured throughout the trailer to show how the
film evolves throughout the trailer. Straight cuts are often used in
all trailers to move the picture on faster, Sometimes the simpler
editing techniques are the most effective.
Slow motion is used when the boy and dolphin are underneath the
water to show the steady relationship that the boy and the
dolphin have. The slow motion shows that they both for that one
second can just have fun and relax. This adds some emotion to
the scene where the audience will see the relationship forming
between the two characters.
The text overlay shows which actors feature in the movie which
would draw more attention to the trailer as fans of the actors will
want to watch another film from that particular actor.

3. Camera.
The wide shot image at the beginning of the trailer shows the
location of the paradise beach. You immediately think of
what animals are on the paradise looking island. Then two
seconds later a dolphin is alongside the boat, Jumping. You
will be drawn to this trailer as you will want to watch the
film to pretend you are on that island soaking up the sun.
Their also is a high angle shot of the Dolphin in the sea, this
may have been done to show how vulnerable the Dolphin is
and also how alone he is. They both want a friend and it so
happens they find each other.

4. Sound & Mise en Scene.
The Non Diegetic sound of the soundtrack is a fun
happy song which is common in family film trailers as
they connote how the film itself is. The soundtrack
then changes quite dramatically to connote the danger
of the hunters shooting the dolphin.
The location of the movie is set on an island, which links
with the main character of the dolphin as we usually
think of dolphins on island surrounded with water and
this is what we can see here.
