Comment: Hmm. I'm not sure the world needs another Native movie about despair, abandonment, and revenge. Seems to me filmmakers have tackled those themes enough already.
Also, Lanai's character defines "callous" as a thick patch of skin in the trailer, but that word is spelled "callus." Unless he intended the title to have a double meaning, that's a big oops.
Marcos Akiaten as Blackfoot's brother is the only Native actor I recognize in the cast. But there may be others.
Anyway, you can watch the trailer at the official site. Get ready with the volume controls, because the site launches with loud music that you can't turn off.
