What is Comic Con?

An annual four-day event, started to be a get-together for sci-fi fans to trade comic books in 1970, is now the largest comic book convention of its kind, with over 130,000 people attending guest panels and visiting the venues featuring paintings, comics, movies, TV shows and gaming programs.

Comic-Con International is officially underway in San Diego. The annual convention has established itself as the launching pad for some of Hollywood’s most-anticipated movie trailers and television previews over the years.

Among the big premieres at this year’s San Diego Comic-Con are the first trailers for James Wan’s oceanic superhero movie Aquaman and M. Night Shyamalan’s crossover film Glass, as well as early peeks at The Walking Dead season 9 and Star Trek: Discovery season 2, among other projects.

Here are some of biggest Comic-Con trailers and movie previews of the weekend


The first trailer for the film premiered during the WB studio’s crowded, two-hour panel on Saturday was Aquaman.

Godzilla: King of the Monsters

Warner Bros. Pictures’ movie panel also debuted the Godzilla: King of the Monsters, which will extend the connection between recent monster movies Godzilla and Kong: Skull Island and build on the studio’s plans for a cinematic universe of giant monsters.

M. Night Shyamalan brought the first trailer for Glass to Comic-Con, giving audiences a peek at a film almost 20 years in the making. The film brings together several characters from 2000’s Unbreakable and 2016’s Split, including Mr. Glass (Samuel L. Jackson), The Horde (James McAvoy), and David Dunn (Bruce Willis).


The Walking Dead

The cast of AMC’s hit zombie drama made the trip to San Diego for Comic-Con, and the Friday, July 20, panel for The Walking Dead featured the debut of the first full trailer (see above) for the series’ ninth season — the last one for longtime series star Andrew Lincoln, the actor confirmed.

AMC previously released a teaser (see below) for the show’s upcoming ninth season, and the Comic-Con panel offered lots of reasons to ponder who will survive the series’ next story arc.

Star Trek: Discovery

the first trailer for the explosive second season of Star Trek: Discovery, which debuted in San Diego. Played by Anson Mount, Pike has a long history with the franchise (including the film reboots) and offers a fun connection for CBS’ popular new series. He’s dropped smack dab into the middle of the action in the first trailer, taking over the Discovery as captain.
