Attendees at San Diego Comic-Con were given a treat last weekend when showed a sneak peak of the upcoming Godzilla sequel. Now that footage has made it online.

While not revealing much about the plot, we do hear some of the legendary monster in the trailer.

New cast member Millie Bobby Brown is shown alone, attempting to contact someone or something named ‘Monarch’ via a ham radio. The moment she mentions ‘Monarch’, we hear a roar over the frequency.

The clip, available to see below, seems also aimed at Stranger Things fans.

Brown played Eleven in the hit Netflix series and she’s seen in the trailer making the same iconic hands over ears position she made in the show.

Meanwhile, the use of retro technology also evokes the 1980s set sci-fi.

Godzilla: King of the Monsters will be the latest in production company Legendary’s MonsterVerse, following 2014’s Godzilla reboot and 2017’s Kong: Skull Island.

King Kong and Godzilla will then team up in the aptly named Godzilla vs. Kong in 2020.

Starring in Godzilla: King of the Monsters along with Brown is an ensemble cast of Kyle Chandler, Vera Farmiga, Bradley Whitford, Sally Hawkins, Ken Watanabe, Thomas Middleditch and O’Shea Jackson Jr. Michael Dougherty (Krampus) is directing.
