John Wayne later said John Farrow "didn't really have a great deal to do with" the film. "Everything was set up before he came on it... It was written and I went out and looked for locations and picked the locations where each scene would be shot. I went back and brought the cameraman, and they said there's no color here. I said wait until I show you, and within seventeen miles of town I had white molten rock, blue pools of water, black buttes, big chalk-white buttes. We were using 3-D. We made it in 3-D but then it was never released in that, because Warner Brothers decided to give up and use the Fox system."
