From the introduction:
Each of you plays a specific and important role in the film-making process: the Script Writer, Financier, Company Actor, and Cinematographer.
...
The roles can be played as any race, gender, religion, sexual orientation, etc. The only things known about the characters are the things written below. If you think of something that would be interesting to establish about your character, make it so! Figure out a way to interject it into the discussions you have about the films, before and after they are made, with the other characters.
