If
you've ever seen a screenplay,
you'll notice that the story
is broken down into scenes.
This is all a screenwriter
is responsible for. It's
the director's job to break
the screenplay down into
a shooting script (the numbered
scenes indicate that the
script is a funded project).
Since the script is already
broken down into scenes,
you must break it down further
into shot coverage. This
means every camera angle,
every single "shot"
of your scene coverage must
be defined. This is what
you base your storyboard
upon. Each shot is based
upon the scene number, followed
by a letter. The letters
designate the exact shot
within each scene. Also,
two letters, I and O should
be skipped because they
look a lot like zero and
one to an editor trying
to read a slate on film.
After you've finished crafting
the shooting script, you'll
have completely made this
movie at least once in your
head and eliminated some
problems.
