ABOUT US
UMA FILMES
From what perspective do we explain the world?
We produce authorial documentaries directed by women, with a predominantly female technical and creative team. These films touch our hearts with their courageous, gender-conscious essence and are rooted in a strong social and political commitment. Stories that engage with the present and challenge historical silences.
Motivated by the lack of diversity of perspectives in cinema, we seek to open spaces for reflection from a perspective that is still underrepresented in the industry: the perspective of female authors.
