May is looking like a stacked month for blockbusters and maybe one of the most anticipated films is Godzilla: King of the Monsters. The sequel will pit Godzilla against classic kaiju like Mothra, Rodan, and King Ghidorah, but fans can count on seeing some easter eggs to other monsters. O’Shea Jackson Jr., who stars in the film, is a big fan of Godzilla and he was geeking out over all of the references he was seeing.

Godzilla: King of the Monsters is already packed with all the monsters you can ask for, but sharp-eyed fans might be able to spot some callbacks to other monsters that Godzilla has beaten to a pulp. In fact, there are theories that more monsters (or Titans as they are called in the sequel) will pop up before the credits roll. O’Shea Jackson Jr. obviously can't give away anything specific, but some easter eggs will send moviegoers rushing to the internet to look up what they just saw.

Oh yeah, I’ve been nerding out really hard. There’s some I can’t really speak of – but we definitely give you – you get that monster in the movie, and you’re going to go on the internet immediately after.

O’Shea Jackson Jr. stars in the film as a colonel who leads a military squadron that runs missions directly related to the Titans that are hidden across the world. Jackson wanted to be in the film because he's such a huge fan of Godzilla and told Collider that he was nerding out hard noticing all the references to other Godzilla films.

Being a fan of the franchise, it must have been a real treat for O’Shea Jackson Jr. to be in the sequel -- especially one where Godzilla takes on his arch-nemesis Ghidorah. Indeed, the coolest part of the movie to Jackson was pretty much anything that had to do with the lightning-breathing three-headed dragon.

Just to speak as a Godzilla fan for a minute, there’s no way in the world Ghidorah is supposed to be in the second movie, and I’m in it? I’m losing my mind, like anytime Ghidorah gets mentioned, I’m like, ‘No way. No way! He’s going down. He’s not going up.’

Based on the trailers alone, I'd say I have to agree with Jackson that Ghidorah looks rad as hell, and I'm pumped to see him in action. If you thought the 2014 Godzilla was light on action, then this sequel is definitely trying to make up for that.

Godzilla: King of the Monsters is all set to arrive in theaters on May 31.
