Never go up to an African and say “Hakuna Matata” (I know lots of you will still do it, LOL).

The producers used an African National Park called Hell’s Gate National Park in Kenya as the setting of this movie.
“hakuna matata“- Swahili phrase which means “There are no worries.”
Look at the picture below: Swahili is spoken in East African Countries (Info from Stanford.edu; click on the picture to read the full article). Yellow shaded regions are countries where Swahili is spoken the most.
*Never assume they know the language, it is more wise to ask first*
