"Punishment comes one way or another"
This is made from the same book as the 1969 film with John Wayne. Again, the girl Mattie falls into a mine and sees a dead body. She pulls on the shirt of the body and sees some snakes inside it. We see a bunch of fake computer-animated rattlesnakes crawl out from under the coat. One crawls around her neck and she throws it off. Another crawls up to her hand and just bites it without striking it the way rattlesnakes do, as if it was sampling some potato salad at a deli. Rooster Cogburn comes down into the mine and with four shots kills them all, cowboy style, then cuts x's on the bite holes on Mattie's hand and sucks out the poison.
Cogburn rides his horse to death then carries Mattie to a cabin for help and later we learn that her hand turned black and she lost her arm because of the snakebite. We see a brief shot of her with a missing arm at the end. All this could have really happened, but I have to wonder why they didn't use at least some real snakes along with the fake snakes. They didn't even insert the cliche close-up shot of a live rattlesnake, then switch back to the fake snakes. Maybe they should be praised for not doing that. Whatever, I actually prefer this movie to the 1969 movie.
