While certain franchises have made the leap from PG-13 to rated R, it makes sense why the MonsterVerse probably won’t follow suit. Right now, Godzilla vs. Kong is seven months away from release, but as far as ticket sales are concerned, it’s more likely to draw a bigger audience by staying in PG-13 territory rather than taking a risk and making it rated R.
Godzilla vs. Kong smashes into theaters on March 13, 2020 and the prospect of Godzilla and King Kong in combat with all the gore on full display is definitely an exciting prospect for adult fans, but the call to children is up for question. As Director Adam Wingard mentioned in his interview with Gormaru Island, these kinds of action blockbusters need to appeal to as wide an audience as possible, though Wingard noted the irony of this considering his two favorite movies as a kid were both R-rated.
There have been discussions about future movies and characters that could be introduced, but as it stands now, Godzilla vs. Kong will be the last MonsterVerse installment on the calendar until Warner Bros is able to see how it performs. After then, they will decide whether to move forward, press pause and make changes, or just end things there.
By the end of the year, we should hopefully know what rating it will receive from the MPAA (Motion Picture Association of America).
