Who is the "James Waller" producers are always thanking in the credits?

I was scrolling through the credit page for Ready Player One on IMDB and noticed the very last credit was a "Thanks" to James Alexander Waller. His IMDB page doesn't have any info, but he certainly gets thanked a lot. Google was also not super helpful. Is this a joke I'm not in on? Or a reference I'm just not understanding?
