This presentation focuses on the making of French mini-series. Why create a mini-series rather than a series or a feature film? Is it the subject that dictates the format? Or is it rather production and financial strategies that underlie such a choice? How do you write a mini-series? Is it also written by several people? Is orality as present in the creative process as it is in a series? Using primary sources (script documents, interviews, etc.), the aim is to conduct a pragmatic analysis that will allow us to better define the writing process of a mini-series and to understand the reasons for it, but also to propose a socio-economic analysis that questions the choice of such a format.
