In live-action, writing, production, and editing happen in discrete stages. In animation, they overlap - happening simultaneously. This allows a real dialogue to occur between the writer, the director, the actors, and the editor, and it makes the writing process a lot more collaborative and a lot less lonely.

I can write two scripts concurrently, but I usually prefer to do one at a time. However, I also usually have 5 or 6 story ideas that are percolating in my head at any one time, so it can get a little crowded in there.
