"The talkies are the only art that would attract Leonardo da Vinci were he alive to-day. It is the only art that excites a scientist's curiosity, the only art that challenges the engineer, the only art that offers the great artist a medium capable of expressing every human thought and emotion, as well as the pure aesthetic effects of color and music. It is a baby giant, as clumsy as all babies are. Its noises are, we grieve to admit, often as inartistic as the squalling of a baby. But squalling babies have a way of growing up into soft-voices women and great singers. This is why we, the authors, have gladly played the role of nursemaids. We don't know what the baby will be doing and saying when it grows up. But we are sure it will make its mark in the world."
