Nathalie Masduraud trained at Fémis and has been active since the 1990s. She makes documentaries, in particular portraits of artists, notably Ella Fitzgerald and Françoise Sagan. Valérie Urrea makes documentaries on social issues such as gender, race and disability. She is also interested in dance, making several films about the choreographer Mathilde Monnier.

Valérie Urrea and Nathalie Masduraud made their first film together in 2014, Afrique du sud - Portraits chromatiques, a documentary dedicated to the South African photography scene produced by Arte, accompanied by a mini-series. The theme of photography featured again in their next film, Focus Iran, l'audace au premier plan (2017), a portrait of the young Iranian scene, shot through the prism of photographic practice and taken further in the web-series Iran#NoFilter. 

In 2019, Nathalie Masduraud and Valérie Urrea are returning to a format that has been close to their hearts since the beginning: the artist portrait. Through the prism of Un barrage dans le Pacifique, the famous autobiographical novel by Marguerite Duras, they also touch on another aspect that runs through her work: the study of colonial dynamics. Pornotropic, Marguerite Duras ou l'illusion coloniale is a testimony to Duras' modernity and radicalism through a collection of archival interviews with the writer, readings and contributions from specialists in her work. Having experienced poverty in Indochina, on the side of the colonisers, the young Marguerite quickly perceives the hypocrisy and violence that emanate from a bourgeois society that imposes its domination through crude morality. 

It was a news item about a woman who was the victim of a sexist attack that finally prompted Nathalie Masduraud and Valérie Urrea to create H24, 24 heures dans la vie d’une femme, an ambitious transmedia project featuring the contributions of twenty-four female authors. These include Christiane Taubira, Alice Zeniter and Chloé Delaume, whose words are spoken in each case by a different actress. 

The cast of the twenty-four episodes of this web series, whose short formats were designed to reach a young audience through social media, includes actresses such as Camille Cottin, Diane Kruger and Déborah Lukumuena. The films share a common principle: at the beginning of each story, a real news item, corresponding to a moment in the 24 hours in a woman's day. While Nathalie Masduraud and Valérie Urrea directed several episodes of H24 themselves, they have also invited other directors, including Charlotte Abramow, Sandrine Bonnaire and Nora Fingscheidt, to work in this new format, also available in book form.
