Rod Serling, the American screenwriter & television producer best known for The Twilight Zone (watch full episodes here), fielded questions from students about the whole art of writing for television. In the clip above, he gives a rather dramatic response to the question, “Where do ideas come from?” (They come from the Earth… They’re in the air. And, to put them on paper, you bleed!) If you keep watching this YouTube playlist, the conversation with Serling continues for a good while. This contribution was sent to us by Elan, who dates the clip to around 1972.
