AMC has revealed a new trailer for The Walking Dead season 10, which made its way online after making its debut at San Diego Comic-Con. While many trailers and announcements at SDCC take pop culture lovers by surprise, The Walking Dead has become a staple of the event over the course of the last decade. This year is no different when it comes to San Diego Comic-Con, and we now have our first look at the upcoming season, which won't feature Andrew Lincoln as Rick Grimes and, additionally, will be the final season to feature Danai Gurira as Michonne.

Moderator Chris Hardwick announced that The Walking Dead Season 10 will premiere on Sunday, October 6 at 9pm. The premiere episode is written by showrunner and executive producer Angela Kang and directed by executive producer Greg Nicotero.

The Walking Dead executive producer Gale Anne Hurd announced that Thora Birch (American Beauty, Clear and Present Danger) will join the cast as Gamma in the upcoming 10th season. Gamma is a Whisperer sentry fiercely protective of Alpha. She is a believer and committed to the Whisperers' way of life. In addition, Kevin Carroll (The Leftovers, Snowfall) joins The Walking Dead cast as Virgil, a highly intelligent and resourceful man who is desperately trying to get home to his family.

Not much else had been revealed about what to expect from this upcoming season ahead of the trailer debut. Showrunner Angela Kang had teased that they will be exploring themes of Paranoia and PTSD this time around, in addition to the threat of fire. That may sound silly, but in a world with now firefighters, that can be problematic. Kang also revealed that we'll be picking up roughly a few months after the season 9 finale. So we shouldn't expect another huge leap forward in time like we experience last year following Andrew Lincoln's departure. But this does serve as our first real look at the survivors and what they'll be up against in the upcoming batch of episodes.

AMC has no plans on ending The Walking Dead universe, yet it's an interesting road ahead. They've seen ratings plunge for the flagship series during the past few seasons. Despite the fact that many critics and fans felt like the series really improved last year, it hasn't actually helped bring viewers back. Now, they have to contend without Rick and, at some point during this year's run, they're also going to have to deal without Michonne, who has been a fan-favorite character ever since she debuted.

Despite that, the network is expanding the universe, rather than walking things back. Aside from Fear the Walking Dead, they also have a third series in development that will center on the first generation of people to grow up in the zombie apocalypse. Andrew Lincoln is also set to return as Rick Grimes in a trilogy of Walking Dead movies, even though his time on the show has come to an end. This also comes not long after it was revealed that Robert Kirkman decided to end The Walking Dead comic book series that the show is based on with its most recent issue.

The creative team behind the scenes for the series includes Robert Kirkman, Dave Alpert, Gale Anne Hurd, Greg Nicotero and Scott M. Gimple, who oversees the whole Walking Dead universe for AMC. The cast for season 10 includes Norman Reedus (Daryl), Melissa McBride (Carol), Danai Gurira (Michonne), Ryan Hurst (Beta), Jeffrey Dean Morgan (Negan), Avi Nash (Siddiq), Nadia Hilker (Magna), Eleanor Matsuura (Yumiko) and Cailey Fleming (Judith). Be sure to check out the new trailer for yourself. The Walking Dead season 10 returns to AMC this October.
