"He's incredibly imaginative. But also, the thing I've found, looking at his work, is that he's primarily a science fiction writer. And all the science stuff that's in his stories is fairly accurate - he did a lot of research. For example, in From Beyond, he did a lot of research into the pineal gland; in Reanimator, he almost gives you the formula for bringing the dead back to life. I think he was very interested in how things actually worked."
