At San Diego Comic-Con today, Warner Bros. used its Hall H panel to show off its work on not just three films, but the latest installments in three different major franchises: Fantastic Beasts, DC, and its monster films. Among them: the first trailer for its upcoming film Godzilla: King of the Monsters, the sequel to Gareth Edwards’ 2014 film Godzilla.

The trailer kicks off with Millie Bobby Brown (Stranger Things) fleeing a disaster as a scientist (Vera Farmiga) explains that we’re experiencing a new threat — the “fever” sent to fight the “infection” that humanity has become — as monsters like Godzilla are returning to the Earth after remaining in hiding for years. “Unless all the Titans are found,” she says over a surprisingly effective “Clair de Lune” synch, “our planet will perish, and so will we.” It looks as though there’ll be more than just Godzilla here as well: Mothra makes an appearance, as well as several monsters, teasing some major clashes between the film’s titular hero and those that would challenge him.

Gareth Edwards was originally expected to helm Godzilla: King of the Monsters after it performed well at the box office in 2014, but left and was replaced in 2016 by Michael Dougherty. The film the latest installment of its own cinematic universe: last year, Legendary Pictures assembled a writer’s room to develop the path to bring together Godzilla and King Kong into one massive battle. Godzilla: King of the Monsters is the next film in that larger story, and Godzilla vs. Kong (directed by Adam Wingard) is expected to hit theaters in May 2020.

Godzilla: King of the Monsters hits theaters on May 31st, 2019.
