Fuller, who works for Michael Bay's Platinum Dunes company, told Sci Fi Wire that he is close to hiring an A-list writer for the Hasbro board game spinoff.
He said: "I don't think we've closed the deal, so I can't say, but we've got a very high-level writer to write that, and we start writing it, I think, within the month."
Elf's David Berenbaum has previously worked on the script.
Fuller added that Ouija will be "a huge movie. That's a big, big, big thing. It's more like a Pirates Of The Caribbean adventure story, with a Ouija board at the centre of it".
Hasbro began selling Ouija boards as novelty items in 1966. In the game, participants place their hands on an indicator which moves across the board to spell out messages apparently from spirits.
