for every part, however small.

One thing that you should _not_ overlook in making up your list of
characters, we repeat, is to show the director how he may cast his
available people to the best advantage. To do this, you should not
only mention every character, no matter how unimportant, but in the
case of all those characters who do not actually come under the head
of principals in that particular picture, you should give the number
of the scene or scenes in which they appear. This will, in many cases,
enable the director to use some of his people in more than one
character by "doubling" two minor roles.

As an example, let us suppose that you have written down your
principals--the ones who will keep the one part through the whole of
the action. You can then write:

Mrs. Brown's maid, in 9 and 11.[15]
Trained nurse, in 22.
Policeman, in 15.
Blind beggar, in 27.
Colored porter, in 28.

[Footnote 15: Meaning _scenes_ 9 and 11. Of course, you can only make
this arrangement _after_ your scenario has been blocked out, scene by
scene.]

Here are five minor characters, and yet, if the director desired, he
could use only two people to play all five parts. Mrs. Brown's maid in
9 and 11 could easily change to a trained nurse for 22. The actor
playing the policeman in 15 could just as easily make up as a blind
beggar for 27; and he would then be able to change again and go on as
a colored porter in 28, the next scene.

A point that many who are not familiar with the inner workings of the
studios do not realize is that although Scene 10, let us say, is
"done" on one day, Scene 11 may not be taken until the following day,
or even a week later. It frequently happens that one set is allowed to
stand for several days, on account of "re-takes" that have been found
necessary, or because a director has difficulty in obtaining a certain
lighting effect. In such cases certain players are required to play
the same part over and over again, even though between the "re-takes"
they may "work" for other directors in the same studio.

_6. Actual Work on the Cast_

You will probably find that the best and easiest way to prepare your
cast of characters is to keep a rough list of all the people who take
part in the action, as you write the scenario. Because, of course,
although the cast of characters is the second division of the script,
it should have its final preparation after the scenario has been
comple
