Directors in Development
Directors can become involved with a script at any stage of development. Many directors write their own projects and, as such, would be involved from the start. Others may attach themselves to stories at the point that development is drawing to a close.
Once they confirm their commitment to a project, directors will work with the writer and producer towards completing a shooting script that they are happy with and feel is ready to film. At this point, the director takes the lead on turning the vision for the film into a reality.
Directors often gain experience in the industry for many years before being trusted with creating their own film. It is key that they have a strong understanding of the entire film-making process and have frequently worked in multiple roles to obtain that knowledge. In particular, great familiarity with production is a must.
Fundamentally, anyone trusted with any kind of significant budget almost always has a track record in directing. This can range from making short films, working in television or transitioning from theatre.
