When that voice happens to be elegant spoken French, it disconcerts the viewer and challenges attitudes-exactly as Ms Diop intends it to in " Saint Omer" .
Diop welcomes the help, saying it is important to start making drones locally before foreign companies come in and begin selling them at much higher prices.
When collecting two prizes at the Venice Film Festival last year, Ms Diop nodded to Audre Lorde, a black American feminist: " Our silence will not protect us."
Though not all materials necessary to make the drone are available in Senegal, Diop says he wants to prove that it's possible to build one in his home country.
