Director of course refers to the work of the director on a film production whose responsibilities include everything from pre-production (see casting) to the finished work (see editing) as well as being the key artistic and creative mind behind the production. A Director usually comes to the project, before the start of filming, with concrete ideas of how the finished product and its various components should look. This applies to all types of production, (e.g. theater, cinema, television, video) and what genre (e.g. action move, documentary, music, film, video, animation, commercial), and what length.
