Griffith was always ready to take tremendous risks in his films and in his business affairs. He was always ready to fly too high. And in the end, the wings of fortune proved, for him, like those of Icarus, to be made of nothing more substantial than wax and feathers. And like Icarus, when he flew too close to the sun, they melted, and the man whose fame exceeded the most illustrious filmmakers of today, spent the last 17 years of his life shunned by the film industry he had created.You've already dropped the wax and feathers. It's time for some new wings.
I've compared Griffith's career to the Icarus myth, but at the same time I have never been certain whether the moral of the Icarus story should only be, as is generally accepted, 'don't try to fly too high,' or whether it might also be thought of as 'forget the wax and feathers, and do a better job on the wings.'
Here's a link to the video of Kubrick's speech for anyone interested.
