There’s a Star Wars movie ( a new hope) dubbed in Navajo. It’s close to the original dialogue. Some parts of the dialogue in Navajo made me lol. I liked it. I’ve heard there’s a Finding Nemo Navajo version but I have not found it.
The Navajo language isn’t being passed down the generations. It was so unknown, hence the code talkers (other NA languages, too) back in WWI. Can’t see how many NA millennials would understand movies without closed captions. But, hey, diversity is soooo waaaay coooool!
