CriesofthePast:
I guess during the application process, people could suggest what kind of movie they'd like it to be, and we can see how you feel about what would work best.
I actually thought about having players reply with their Audition/Demo Reel, and state a role they were applying for in terms like Action Lead, Romantic lead, Sidekick, Comic Relief, Subject Matter Expert, etc. Doing it that way seems like it would be a good way for me to decide from the applications what sort of film would be the best to start. Plus the Audition/Demo Real process already exists in the system whereby players define rolls based on the use of an associated talent or by sheer fame.
I think I might actually go with using applications to define the movie and have rejections possibly play Co-Star or Extra Roles under my control.
