Is a writing agent a writing agent, or do they specialize in a certain field? If I'm working on a teleplay, or a screenplay, would the same agent handle that as a novel? Or does it all depend. Right now I have an idea for a spinoff series of a current series that I'm super stoked about. I have great ideas on how to wrap up the universe that has already been created, but I don't know how to begin. Do I have to start with a treatment, and would an agent even look at something I do for an already existant show if I haven't created something unique and of my own? I don't particularly know how to get my foot in the door on this one. Unless I go to a comicon and bug the hell out of the creators.
