Millie Bobbie Brown and Vera Farmiga star in “Godzilla: King of the Monsters.”

The annual San Diego Comic-Con is the biggest pop culture extravaganza of the year. The four-day convention, which wrapped up Sunday, revealed sneak peeks of several upcoming movies, from comic book films to much-awaited sequels.

Here’s a look at the newest trailers to come out of Comic-Con.

“Godzilla: King of the Monsters”

The trailer for the third film in Legendary’s MonsterVerse of giant monsters looks excellent. After 2014’s “Godzilla” and 2017’s “Kong: Skull Island,” “Godzilla: King of the Monsters” brings back the atomic-breathing monster in an apocalyptic adventure – and he’ll be fighting some old friends.

The trailer shows the three-headed dragon King Ghidorah, giant moth Mothra and flying pteranodon Rodan, referred to as the Titans. As Godzilla vies against the classic monsters for supremacy, the world’s fate hangs in the balance.

With beautiful blue, orange and red hues, the film looks gorgeous, taking inspiration for its look from the bright color palette of “Kong: Skull Island.” The trailer also promises to show more of Godzilla himself, which the 2014 “Godzilla” needed more of.

The human cast includes a captivating Millie Bobbie Brown (“Stranger Things”), Vera Farmiga, Kyle Chandler, Charles Dance and the return of Ken Watanabe and Sally Hawkins from the 2014 film.

“Godzilla: King of the Monsters” invades theaters May 31, 2019.

“Shazam!”

With Marvel Studios absent from Comic Con, DC Comics brought the goods to Hall H this year. The Warner Bros./DC Extended Universe unveiled great trailers for the next two comic book movies on its slate, “Shazam!” and Aquaman.”

The fun and kid-friendly “Shazam” brings light to the DC Universe. The story follows Billy Batson (Asher Angel), a boy who can turn into an adult superhero (a wonderfully goofy Zachary Levi) by saying a magic word.

The movie looks like a superhero version of “Big,” but is there anything wrong with that? Not judging by the humorous trailer. You can’t help but smile watching Levi figuring out his superpowers in what looks like a funny and enjoyable outing.

“Shazam!” blasts into theaters April 5, 2019.

“Aquaman”

My man! After a standout performance in “Justice League,” Jason Momoa returns as the underwater superhero who can talk to the fish (and other sea creatures, as we see in the trailer).

Arthur Curry/Aquaman is called home to the underwater kingdom of Atlantis to challenge the rule of his brother (Patrick Wilson), who seeks a war with the surface world. Under James Wan’s distinctive direction, the film offers beautiful underwater sequences and cool shots, such as people riding sharks.

The first DC film after “Justice League,” “Aquaman” promises goofy fun and a charismatic hero in Momoa. Together, “Aquaman” and “Shazam!” could be what the DCEU needs to turn the ship around after the underperforming “Justice League.”

“Aquaman” swims into theaters Dec. 21.

“Fantastic Beasts: The Crimes of Grindelwald”

The sequel to 2016’s “Fantastic Beasts and Where to Find Them” moves the magical action to Paris. The new trailer focuses more on young Hogwarts professor Albus Dumbledore (Jude Law) and his efforts to find the dangerous dark wizard Grindelwald (Johnny Depp).

As Dumbledore can’t move against Grindelwald himself (for reasons as yet unknown), the professor seeks out former student Newt Scamander (Eddie Redmayne), who returns with some familiar magical creatures and encounters some new ones. Also returning is Credence Barebone (Ezra Miller), an Obscurial wizard who was believed to have died in the previous film.

The visuals in the trailer are stunning in what looks to be a darker chapter in the world of Harry Potter.

“Fantastic Beasts: The Crimes of Grindelwald” casts its spell Nov. 16 in theaters.

“Glass”

M. Night Shyamalan brings together the storylines of his beloved 2000 film “Unbreakable” and last year’s break-out hit “Split” in “Glass,” creating a cinematic universe among his own films.

The trailer for “Glass” unites the three main characters from the two movies in a mental hospital. Security guard-turned-superhero David Dunn (Bruce Willis) and mentor-turned-villain Elijah Price/Mr. Glass (Samuel L. Jackson) from “Unbreakable” meet Kevin Wendel Crumb (James McAvoy) from “Split,” a man with dozens of multiple personalities who abducted young girls in the previous film.

Dr. Ellie Staple (Sarah Paulson) explains that she is treating the men for a growing disorder where people believe they are superheroes. While David and Kevin seem like natural enemies, Kevin and Glass are poised to team up, with a lot of lives hanging in the balance.

While “Unbreakable” was a superhero origin story before the genre took off, “Glass” comes out amid the wave of comic book flicks. Hopefully it’ll offer more commentary about superhero films in a world dominated by them. I’m excited to see how Willis, McAvoy and Jackson – all of whom have starred in comic book-based franchises (“Red,” “X-Men” and the Marvel Cinematic Universe, respectively) – come together and square off.

“Glass” shatters in theaters Jan. 18.
