"'Godzilla 2' is being directed by 'Trick ‘r Treat' and 'Krampus' director Michael Dougherty, who co-wrote the script with Zach Shields. (Don’t forget Dougherty also co-wrote 'X-Men 2,' so his geek credentials are firmly established.) Kyle Chandler, Vera Farmiga, and 'Stranger Things' breakout Millie Bobby Brown will play a family at the center of the action in this film, and they’ll be joined by O’Shea Jackson Jr., Thomas Middleditch, Zhang Ziyi, Bradley Whitford, Charles Dance, and Aisha Hinds. We’ve known for a while that Ken Watanabe would return and reprise his role as a Monarch agent from the 2014 reboot, but now we have confirmation that Sally Hawkins will be back as well.
Godzilla will square off against Mothra, Rodan, and King Ghidorah, as promised at Comic-Con way back in 2014. Check out 'Godzilla 2’s' official synopsis:
'The new story follows the heroic efforts of the crypto-zoological agency Monarch as its members face off against a battery of god-sized monsters, including the mighty Godzilla, who collides with Mothra, Rodan, and his ultimate nemesis, the three-headed King Ghidorah. When these ancient super-species—thought to be mere myths—rise again, they all vie for supremacy, leaving humanity’s very existence hanging in the balance.'" - via /Film
