In this article, I reflect on the intersection between feminism and documentary art as truth-telling by focusing on Alcaldessa ( Ada Colau for Mayor), the most relevant documentary of the long-term collaboration between the film-maker Pau Faus and Ada Colau, the first female mayor of Barcelona (2015–2023). My argument is critical of a reductionist interpretation which portrays Alcaldessa as a personalist postfeminist documentary overly fixated on ‘biography rather than policy’. In contrast, I posit that Faus’ documentary, delving into Colau’s initial electoral campaign (2014–2015), offers valuable insights into pivotal aspects of an underexamined political vision that merges the principles of new municipalism with a focus on the ‘common people’ ( gent comú) and feminism. Furthermore, the documentary sheds light on unreconciled dilemmas inherent in the lived new politics and feminist leadership, issues that often remain concealed within the ideological trappings of political manifestos and programmes.
