J. K. Rowling afirmou que ela não gosta de fantasia, e não lhe ocorreu que Harry Potter era uma fantasia até depois dela ter escrito, de acordo com uma entrevista em 2005 com a Time Magazine .
The most popular living fantasy writer in the world doesn't even especially like fantasy novels. It wasn't until after Sorcerer's Stone was published that it even occurred to her that she had written one. "That's the honest truth," she says. "You know, the unicorns were in there. There was the castle, God knows. But I really had not thought that that's what I was doing. And I think maybe the reason that it didn't occur to me is that I'm not a huge fan of fantasy." Rowling has never finished The Lord of the Rings. She hasn't even read all of C.S. Lewis' Narnia novels, which her books get compared to a lot.

Hang on--other things? It's disconcerting to think of Rowling stepping out on Harry and the gang with another set of characters. But at least we can say Harry is Rowling's last wizard. From here on out, it's Muggles only. "I think I can say categorically that I will not write another fantasy after Harry," she says, making herself and her publicists, who hover nearby, visibly nervous. "Wait, now I'm panicking. Oh, my God! Yes, I'm sure I can say that. I think I will have exhausted the possibilities of that. For me." Beyond that, she isn't giving away many clues, but she's approaching the project with her usual ruthless skepticism. "We'll have to see if it's good enough to be published. I mean, that is a real concern, obviously, because the first thing I write post Harry could be absolutely dreadful, and, you know, people will buy it. So, you know, you're left with this real insecurity."
