Add Khoisaan (Khoesan) languages of the Kalahari Bushmen

https://www.imdb.com/title/tt0059675/

The native Kalahari Bushmen (also known as the San people) who appear in one scene of this movie are speaking their tribal language, which is in a family of languages known as Khoesan, spoken by the Bushmen in the Kalahari desert and surrounding savanna region of southern Africa.

You don't have this language (family) in the list to choose. There are other movies with the Kalahari Bushmen, particularly documentaries, that need to correctly list this language family.

Please add "Khoesan languages" (or if you prefer to spell it the more scientifically pronounced "Khoisaan").
