I saw Ben Stiller's movie Walter Mitty [2013]; it's very beautiful. You look at some of the movies John Ford did with John Wayne and Jimmy Stewart, and then look at Remington and Ansel Adams, and I think you see a connection, certainly in the imagery of the West.
It would be a mistake to ascribe this creative power to an inborn talent. In art, the genius creator is not just a gifted being, but a person who has succeeded in arranging for their appointed end, a complex of activities, of which the work is the outcome. The artist begins with a vision — a creative operation requiring an effort. Creativity takes courage.
