TV tonight: riveting documentary about Nigeria’s female film directors

The foreign affairs series delves into Africa’s burgeoning entertainment industry. Plus: a new generation of big cats. Here’s what to watch this evening

7.30pm, Channel 4
There’s a reason why this Friday evening buzzkill of a documentary strand is approaching its 50th season: it does a brilliant job of finding essential, often bleak stories from around the world and offering a potted guide. This new run begins in Nigeria and the conservative city of Kano, which is home to a prolific film industry. Anja Popp meets Mansurah Isah, one of its few female directors, and explores her battle to elevate women’s perspectives. Phil Harrison
