It wouldn't be Comic-Con without a few surprises here and there, and Warner Bros.' Hall H panel on Saturday morning may have delivered the biggest surprise of the Con. The studio was set to showcase six movies during their Hall H presentation, hosted by Conan O'Brien, two of which were the upcoming DC movies Suicide Squad and Wonder Woman. However, there was a third movie showcased during the panel, the highly-anticipated Justice League, and today you can watch the full panel video.

Host Conan O'Brien first welcomed director Zack Snyder onto the stage, who then brought out the cast shortly thereafter. Ben Affleck (Batman), Gal GadotRay Fisher (Cyborg), Ezra Miller (The Flash) and Jason Momoa (Aquaman) came out to greet the cheering fans, but there was one glaring omission, Henry Cavill. Even though his beloved character Superman "died" in Batman v Superman: Dawn of Justice, most fans assumed he would be coming back to life at some point in the movie. Alas, Henry Cavill was brought out last, although we didn't learn anything about this resurrection at the panel. Warner Bros. debuted the panel video today, although it doesn't include the new trailer that was released just after the panel let out.

Production has been under way on Justice League since April, and we learned quite a bit about the movie over the past few months, but still, many fans weren't expecting the first trailer to debut at Comic-Con, especially since there is still plenty of filming left. Warner Bros. has set a November 17, 2017 release date for this superhero adventure, which will follow two more highly-anticipated movies the studio showcased today, Suicide Squad (August 5, 2016) and Wonder Woman (June 2, 2017).

Fueled by his restored faith in humanity and inspired by Superman's selfless act, Bruce Wayne enlists the help of his newfound ally, Diana Prince, to face an even greater enemy. Together, Batman and Wonder Woman work quickly to find and recruit a team of metahumans to stand against this newly awakened threat. But despite the formation of this unprecedented league of heroes-Batman, Wonder Woman, Aquaman, Cyborg and The Flash-it may already be too late to save the planet from an assault of catastrophic proportions.

Justice League is meant to be the DC Comics movie version of The Avengers, but the tone will be quite different and it is clear that Warner Bros. wants to set themselves apart from Marvel Studios. The movie has a cast that we are largely already familiar with, bringing back Ben Affleck as Batman, Gal Gadot as Wonder Woman, as well as Ezra Miller as The Flash, Jason Momoa as Aquaman and Ray Fisher as Cyborg, who had brief cameos in Batman V Superman. Justice League has also added J.K. Simmons, Amber Heard and Willem Dafoe. Also returning is Amy Adams as Lois Lane, Jesse Eisenberg as Lex Luthor and Jeremy Irons as Alfred. Take a look at this full panel video below, along with the trailer that debuted at SDCC, and stay tuned for more on Justice League, arriving in theaters November 17, 2017.
