It´s not "Mogambo"

It´s quite a long time since we don´t watch together in class any scene of a film. So it´s high time to do so. When deciding which film could be appropriate  I don´t know why this title has come to my mind. A hint: it´s related to Africa, its title is neither "The KING of the Apes" nor "Mogambo", and it´s starred by one of the best actresses in the world, the one who got another Oscar two months ago. Can you guess?
