Nigeria's film industry, known as Nollywood, is reportedly worth as much as $3bn (£2.4bn) a year.

But filmmaker Tope Oshin told BBC Focus on Africa's Mayeni Jones there were fewer than 20 female directors in Nigeria.

She spoke to many of them for her documentary Amaka's Kin - The Women of Nollywood.
