Now that Comic-Con International: San Diego (SDCC) is officially over (hate to see you go!), we’re thrilled to bring you a full list of the previews, first looks, and trailers unveiled at the con, offering fans a glimpse into what’s to come for fans’ favorite franchises and TV series.

New and returning shows, such as She-Ra and the Princesses of Power, The Walking Dead, The Dark Crystal, and Rick and Morty, dropped by the con to reveal what we can expect from their new seasons. 

Check out the major trailers below.


So this one is technically billed as a “sizzle,” but regardless, it’s our first look at the final season of TV’s longest-running superhero show. Brandon Routh is set to reprise his role as Superman during Arrow‘s eighth season, and he made an appearance during the show’s SDCC panel today. The show returns to the CW on Oct. 15.


For those who saw the 2013 dystopian movie Snowpiercer, parts of this trailer will look very familiar: the creepy classroom, the trail hurtling through a frozen world, and the major class disparity on board. In the first footage from the upcoming TBS show, we learn that the story takes place six years after the world froze — about 10 years before the events of the Snowpiercer movie — and covers an earlier rebellion by the tail passengers.


The first full trailer for the third season of this hit HBO show debuted in Hall H, finally giving fans a clearer idea of what this season — which debuts some time next year — will be about. Dolores is out and about in the real world, Maeve is in the World War II world, and there is clearly a robot hunt on the way. The trailer is, of course, beautifully shot (would we expect anything less?). It’s also set to the song “We’ll Meet Again,” and the cheery tune provides a haunting juxtaposition to the characters’ violent struggles on screen.

Star Trek: Picard

The trailer so good that Hall H showed it TWICE! Sir Patrick Stewart closed out the Star Trek Universe panel block with a Q&A and trailer premiere for the upcoming Picard series, airing on CBS All Access early next year. Captain Picard is back and better than ever.

She-Ra and the Princesses of Power

Adora, Glimmer, and Bow are in charge now as they embark on a journey to defeat the Crimson Waste in the upcoming third season of the Netflix series. The new season will see the Princess Alliance back in action as they come face to face with Crimson Waste leader Huntera (played by guest star and Oscar winner Geena Davis).

The Walking Dead

The 10th season, the last for Danai Gurira’s Michonne, will premiere Oct. 6 on AMC, featuring plenty of action in the fight against the Whisperers. A battle is coming: The Survivors must team up to save themselves from the new big bad in the Whisperers. Prior to the premiere, a TWD special will air on the network on Aug. 11.


All hell breaks loose when the apocalypse heads to Preacher with a possibly deadly and action-packed new season. The fourth and final season of the AMC series will debut on Aug. 4 as God’s plan for the universe clicks into place. Jesse, Tulip, and Cassidy make their dangerous way to the Most High, encountering nuclear war, prisons, and heavenly prophecies when the series returns.

The Witcher

The original sorcerers have descended upon SDCC to reveal the first trailer for the new Netflix series based on the bestselling book series by Andrez Sapkowski. The series stars Henry Cavill (with luscious, long locks) as monster hunter Geralt of Rivia with heightened senses and fighting abilities. There are intense battles, powerful witchcraft, and important destinies to be fulfilled when the series drops later this year.

The Dark Crystal: Age of Resistance

Fans at SDCC were treated to a behind-the-scenes look at the intricate artistry behind the upcoming Netflix series. Star Mark Hamill promises the new prequel series, much like the original Jim Henson 1982 film, will feature Fizzgigs as the world of Thra is in peril after the Skeksis corrupt the Crystal of Truth. The three Gelflings who discover this terrible secret embark on a quest to save their world during a period of rebellion.

Carnival Row

Not only did fans get one trailer in advance of the upcoming Amazon Prime series, but they got two, each one exploring the backstory of both Orlando Bloom’s and Cara Delevingne’s characters. Set in the Victorian era, the series introduces a variety of fantasy creatures and immigrants who reside alongside humans as they attempt to live in harmony as neighbors after a previous war saw them as opponents. The two featurettes take fans inside the perspective of Delevingne’s fairy runaway Vignette and Bloom’s orphan human Philo. The first season will debut on Aug. 30.

Rick and Morty

Sound the ominous beeping noise!! Adult Swim revealed a first look at the upcoming fourth season of Rick and Morty. The new clip reveals a mysterious alien character (Taika Waititi) meeting the mad scientist and his nephew, insisting that the tech-savvy alien take down an app making an ominous beeping sound. The animated series will return for 10 more episodes this November as the duo team up with alien Glootie to make a love-finding app.

The Watchmen

A vast and insidious conspiracy is at play in the official trailer for the new HBO series, based on the DC graphic novel of the same name, as masked vigilantes are outlaws in town. The drama series will feature nostalgic moments, quotes, and images from the original novel, as well as new faces and sources of fear during the chaotic time. There are masked superheroes and police investigations running rampant, in addition to Regina King kicking a tremendous amount of butt.

The Good Place Gag Reel

Okay, so this isn’t technically a trailer, but it’s too good not to include. Sadly, fans didn’t get a look at the NBC show’s fourth and final season, but they did get a gag reel from the third season. And, of course, the clip is brought to us by the Bad Place, because they love it when people mess up.


Supergirl returns in season five to fight off formidable foes: super villains, aliens, and even a social media and tech addiction. The series flies back to The CW on Oct. 6.

Harley Quinn

This leading villainous lady is getting a starring role in her own animated series on the streaming service DC Universe. What’s better than watching Harley Quinn kick tons of butt and stand up to the Joker in what already looks to be a hilarious show? Harley Quinn season one will start streaming soon with Kaley Cuoco (The Big Bang Theory) voicing the starring role.

The Flash

Barry Allen will also continue his DC superhero story on The CW when the sixth season premieres on Tuesday, Oct. 8. The villainous Bloodwork (Sendhil Ramamurthy) is working to kill all metahumans, including the Flash and his sidekicks, because they’re a cancer to society. Talk about shade.

Agents of S.H.I.E.L.D. 

Sadly, several Marvel TV series are coming to an end before Disney+ starts streaming titles this year. Until then, fans of Agents of S.H.I.E.L.D. can catch up on season six, which was extended with four episodes, and say goodbye to the agents in its seventh season on ABC.

Black Lightning

The trailers continue for The CW with Black Lightning, which returns for its third season on Monday, Oct. 21. The DC superhero show is becoming a family affair, as Black Lightning’s kids begin to realize their superpowers and train to work together with him to fight the looming Markovian War.

The Expanse

SyFy series The Expanse is making a comeback on Prime Video on Dec. 13. In its’ fourth season, the Rocinante crew lands on a new planet with new problems to face off, including an Earth-mining corporation, desperate Belter settlers, and a deadly protomolecule.

His Dark Materials

A new fantasy TV series is headed to HBO to fill the void Game of Thrones left. Based on the book series by Philip Pullman, His Dark Materials stars James McAvoy, Dafne Keen, Ruth Wilson, and Lin-Manuel Miranda and follows Lyra, a brave girl from another world searching for her missing friend. She uncovers a sinister plot that involves stolen children and a mysterious phenomenon called the Dust.

Star Trek: Short Treks

Another Star Trek series from CBS is approaching its launch date: Star Trek: Short Treks. The mini-series of six stand-alone stories titles include “Ask Not,” “Q&A,” “The Trouble with Edward,” “The Girl Who Made the Stars,” “Ephaim and Dot” and “Children of Mars.” The downside is that only members of the streaming service CBS: All Access will get to see these new stories.


For those viewers who actually agree to pay to watch YouTube, its YouTube Red series Impulse is back for its second season in the fall. “Henry” Coles is gaining control of her teleportation powers and avoiding the people coming after her in the meantime. If you’d like to catch up on the first season, it will be available for free ahead of the season-two premiere.

The Man in the High Castle 

The Prime Video series is set to wrap up in its fourth season. The series delves into a world where the Allied Powers lose WWII. Japan and Germany rule over the U.S., and the Resistance to the Nazis becomes a rebellion and turns into all-out war in the final season.
