People have no idea what Orwellian actually means. When someone says "1984" I automatically assume they mean "Brave New World", and that they've never read either of them.
George Orwell was a fictional person
I see you might have gotten a downvote or two, but for those who don't know, George Orwell is a pen-name. The author's real name was Eric Blair.
No, George Orwell was a professional name for a real person; there's no fictional character.
There are fictional characters that are listed as authors of actual books (Richard Castle comes to mind) but a mere pen name is not a fictional person.
