Okay, a couple of months ago, Legendary announced the "writer's room" they had put together to develop the Monsterverse and to help put together a script for Godzilla vs Kong. The team is headed up by;
Terry Rossio (who wrote an unused script for Tristar's '98 Godzilla). Don't hold that against him, Terry Rossio is one of the most successful scriptwriters of the last 25 years, as his credits include Disney's Aladdin, PotC: Curse of the Black Pearl and Shrek.
J. Michael Straczynski, most famous for creating Babylon 5, Sense8 and the 2011 Thor film.
T.S. Nowlin, who has written the screenplay for Pacific Rim: Uprising.
Patrick McKay, writer for Star Trek Beyond and the upcoming Star Trek sequel.
J.D. Payne, worked with Patrick McKay on the Star Trek films.
Lindsey Beer, something of a wildcard, but she has been announced as the writer for several upcoming projects, including M.A.S.K. (Yes, the 80s Cartoon/toyline), Dungeons and Dragons and the remake of Short Circuit (Johnny 5 is alive?)
Cat Vasko - Who wrote Grrl Scouts
Jack Paglen, writer of Transcendence (2010) and Alien: Covenant
So its a pretty good looking mix of writers, looks like they really want to make sure the shared universe gets off to the right start, especially with J. Micheal Straczynski on the team, his experience with tying together a universe.
Still waiting on that remake of the Beast from 20,000 Fathoms...
