The Lakota people can now enjoy the beloved superhero movie The Avengers in their traditional language.

Star Mark Ruffalo worked with the community to have audio of the 2012 Marvel film redubbed in the traditional language of the Lakota people, whose scant number of native speakers puts the dialect in danger of extinction.

Ruffalo, who produced the 2022 documentary Lakota Nation vs. United States, enlisted his Avengers co-stars, Robert Downey Jr. , Scarlett Johansson and Chris Evans , to rerecord their dialogue for the Lakota version of the film, which also features voice performances from Lakota actors for the more minor characters.

This project came out of my relationship with the Lakota people, Ruffalo said in a video posted to Marvel Entertainments official YouTube channel on Friday.

And it was this fun thing that they wanted to do, where they wanted to take The Avengers this crazy idea lets do a Lakota dub of The Avengers.
