Fisk says the biggest challenge he had on the film was finding the remote locations for shooting. That's largely because, as the movie was shot with only natural light, Fisk had to find locations with a south or southwest vista.
In one striking scene, Glass comes across a heard of bison, leading to a scene with a Native American offering Glass the liver of one of the bison he’s eating. Fisk said that location was found completely by accident.
“We were checking out a river one day, stopped the boats at a point, and walking up this hill we found this large vista,” Fisk said. “The sun was setting, it was the perfect time of day to see it. Everyone thought, ‘My God, this is what we’ve been looking for.’”
Fisk and his team lined the top of the hill with bushes. Computer graphics were used to create the heard of buffalo. Fisk said only one prop bison was created for the liver scene.
“The AD said, ‘Where’s the second one?’ and I told him a man can eat maybe 10 pounds of meat. Between the two of them they wouldn’t even put a dent in it.”
Fisk recalls seeing DiCaprio eat the real bison liver: “I thought Leo was vegetarian, but he went for it.”
