On Concrete Babylon as on other films, after I've found what I feel is a story idea/concept that is good enough that it may be developed in to a film, the first step, or milestone, for me is to make the one-sheet. A one-sheet is a short description of the film containing a key image, story pitch and project description. The reason behind creating the one-sheet is that it sums up the project in a short and easily digestible way that can be used both for external parties, to help get funding, and, more importantly, for the creators to create a stable base to build the rest of the film on top of. The one-sheet also helps in defining the goals of the project and making them more concrete which allows the creators to work more focused and make faster decisions by being able to see if the different choices actually works towards the goals.
