No tears
Clark Gable really didn’t want to cry on camera, worried that sobbing would ruin his image. When Melanie tells Rhett that Scarlett has lost their baby, the news is supposed to make Rhett cry. However, Gable really didn’t want to film this scene and even threatened to walk off set. Fleming agreed to shoot two versions; one with the crying and one with Gable’s back turned, seeming sorrowful. Eventually, Fleming managed to convince Clark Gable that the audience would empathize with Rhett and not feel as though he was weak. The crying scene stayed and was one of the most moving parts of the entire movie.
Seventeen days
It’s no secret that Gone with the Wind went through some serious scripting issues. No one seemed to be happy with it, especially not the actors. George Cukor (the first director) and producer Selznick also came to blows over it. In the end, the entire thing had to be hastily rewritten in just seventeen days. They even shelved a much better version in the meantime! Luckily, they finally managed to get things exactly how they wanted them. Kind of.
