Let’s face it. The 1957 Western “Gunfight at the OK Corral” was not the most historically accurate film in history. But some of the actors went to great lengths to get into character. Jo Van Fleet, who played Kate Fisher (Big Nose Kate), was a method actor who needed inspiration. So to feel what it was like to be an abused woman, she had Kirk Douglas (Doc Holliday) really slap her—hard—during a scene. Another time, a real knife was thrown in her direction during a fight with Doc.
