I think Douglas was a real one-off. He was so clever and so intelligent and so well read in real science that he could make science fiction work as well as it did. And just such fun to have around, he was just such a lovely man. ↗
Even if you only want to write science fiction, you should also read mysteries, poetry, mainstream literature, history, biography, philosophy, and science. ↗
I've loved science fiction ever since I was a little kid, mainly from looking at the covers of science-fiction magazines and books, and I've read quite extensively as an adult. ↗
I did one sci-fi movie. I did 'Gattaca.' I liked 'Gattaca' because that was always the kind of science fiction I really dug, the non-action oriented sci-fi. ↗
