The Revenant gets no votes?
Great movie but... Leo free pouring powder feom his flask and then spitting shot down the bore without wadding or priming and arrows flying out of nowhere in the opening fight scene along with the scene with the bear, closing the open and empty frizzen and the gun firing. It eats at my authenticity meter!
I did like the historical reference to John Coulter at the start, running back into camp naked. Though the real one obviously didn't have arrows hanging out of him and wasn't being chased by Arikara.
