Adam Sandler Movie -- Native American Actors Walk Off ... Netflix Says They're Missing the Joke

A group of Native American actors quit an Adam Sandler movie because they feel it's insulting and racist ... but Netflix says the outraged actors are missing the whole point of the film.

The movie is called "The Ridiculous Six" and is being produced just for Netflix. It's described as a spoof on "The Magnificent Seven" ... starring Sandler, Nick Nolte, Steve Buscemi, Dan Aykroyd, Jon Lovitz and Vanilla Ice.

But the spoofing went too far Wednesday, in the eyes of a dozen actors and actresses who walked off the set. Some of the offending jokes included female characters named Beaver’s Breath and No Bra -- and a scene where an Apache woman urinates outdoors while smoking a peace pipe.

Netflix is defending the Sandler flick, saying it's all a joke. A Netflix rep tells TMZ, "The movie has ridiculous in the title for a reason: because it is ridiculous." The rep says it's intended to be a satire of Westerns and the stereotypes popularized in the genre.

The rep adds ... the diverse cast "is not only part of -- but in on -- the joke."

This wasn't the first day of filming. In fact, Loren Anthony -- one of the pissed actors had previously tweeted how much he was enjoying the project. But after today's walk out he said, "Today work was no bueno, my native women were disrespected and i walked off set."
