The Godzilla sequel will be called Godzilla: King of Monsters.
The Pacific Rim sequel will be called Pacific Rim: Uprising.
Godzilla: King Of The Monsters (which, incidentally, was the name the US version of the original 1954 Toho Godzilla) will be directed by Michael Dougherty (Krampus) and is currently scheduled for release on 22 March 2019. It is part of a shared universe with Kong: Skull Island which will culminate in a Kong V Godzilla smackdown movie (we bet they’re mates by the end).
Pacific Rim: Uprising was previously referred to as Pacific Rim: Maelstrom which personally we prefer, but probably a focus group revealed that most Hollywood execs don’t know what a maelstrom is let alone how to spell it. It is being directed by Steven S DeKnight (Spartacus: Blood And Sand, Marvel’s Daredevil), starsJohn Boyega (Star Wars Episode VII: The Force Awakens) and is due for release on 23 February 2018.
