When I was a kid, my favorite movies were the George Pal version of 'War Of The Worlds,' 'Them,' and 'Invasion of the Body Snatchers.' Those movies were scary! They haunted my nightmares for years, so when I started writing, I wanted to write a story that was just as big and just as scary.

Understanding the laws of nature does not mean that we are immune to their operations.

Tomorrow is going to be different than yesterday, it's going to be a lot different.

Notice how every science fiction movie or television show starts with a shot of the location where the story is about to occur. Movies that take place in outer space always start with a shot of stars and a starship. Movies that take place on another world always start with a shot of that planet. This is to let you know where you are. Novels and stories start the same way. You have to give the reader a sense of where he is and what's happening as quickly as possible. You don't want to start the story by confusing the reader.

What I wish is that people would look beyond the tribbles and see I've written some other books that I really would like people to notice. There's The Man Who Folded Himself, there's The Martian Child, which is about my son and the adoption. There's The War Against The Chtorr, which is my magnum opus, my great epic story.

To say that a writer's hold on reality is tenuous is an understatement-it's like saying the Titanic had a rough crossing. Writer's build their own realities, move into them and occasionally send letters home. The only difference between a writer and a crazy person is that a writer gets paid for it.

In the 20th century, we had a century where at the beginning of the century, most of the world was agricultural and industry was very primitive. At the end of that century, we had men in orbit, we had been to the moon, we had people with cell phones and colour televisions and the Internet and amazing medical technology of all kinds.
