Screenwriter with budget authority and creative control over casting — gatekeeps his own script through production. Director's equal, not subordinate.
Someone who sits on set and simultaneously decides on the production budget holds a different position than a pure screenwriter in an office. The writer-producer combines two roles that are actually contradictory — artistic control over the story with economic responsibility for budget and personnel. This only works if both sides are taken seriously and one is not degraded to a mere formality.
In practice, this means: the writer attends budget meetings when it comes to location scouting. They cannot simply have scenes cut without bearing the consequences themselves — neither financially nor for the story. This changes the culture of discussion. A producer who only wants to cut costs encounters a writer who knows what these savings mean for the dramaturgy. Conversely: a writer-producer cannot simply write million-euro scenes into the script and hope the director will solve the problem. They must themselves grapple with the fact that the implementation must be possible.
The real power of this constellation lies in continuity. While the director disappears after shooting, the writer-producer remains in post-production. They prevent the cut and music from demolishing the story they wrote. This is not control over the editor — it is presence in the process. Many problems arise because the writer's original intent is lost in post. A writer-producer can be the memory of the film.
However, this only works if the division of roles with the director is clear. The sidecar position does not mean co-director — that is toxic. It means: I have a say in casting, locations, editing decisions because I know the text I wrote. The director directs, the writer-producer ensures that the story they wanted to tell also arrives on screen. Sometimes these are two completely different stories — then that must be clarified before the budget is allocated.
