“The silent pictures were the purest form of cinema; the only thing they lacked was the sound of people talking and the noises. But this slight imperfection did not warrant the major changes that sound brought in… In many of the films now being made, there is very little cinema: they are mostly what I call ‘photographs of people talking.’ When we tell a story in cinema, we should resort to dialogue only when it’s impossible to do otherwise.”
— Alfred Hitchcock
