Books + film/TV for Tanzania (safari + Zanzibar) - culture & history for adults + kids 11–13?

Hi everyone! my family and I are planning a trip to Tanzania: safari plus time in Zanzibar. We’d love to read and watch a bit before we go so we’re not just seeing animals and beaches without context.

Looking for:

• Books that help with culture, history, and everyday life.
• Movies or TV series (documentaries, drama, whatever) that give a useful sense of place, Happy to use subtitles.
• Suggestions for adults and for kids roughly 11–13 (they read well but aren’t ready for dense academic stuff; for screen stuff, assume we’ll check ratings / content ourselves).
• Fiction is welcome for books; for film/TV, same. Not only docs.

What would you pack on the shelf and the watchlist? Thanks in advance.
