In April, AMC announced the Walking Dead franchise was expanding to include a third series. According to the network, the series "will feature two young female protagonists and focus on the first generation to come- of-age in the apocalypse as we know it. Some will become heroes. Some will become villains. In the end, all of them will be changed forever. Grown-up and cemented in their identities, both good and bad."

Here's what we know so far about the as-yet-untitled third Walking Dead series (after The Walking Dead and Fear the Walking Dead).

It has some familiar producers. The series is co-created by Scott M. Gimple, chief content officer of the Walking Dead universe and former Walking Dead showrunner, and Matt Negrete, who has been a writer and producer on The Walking Dead for the past five seasons and whose credits include Andrew Lincoln's final episode and the Negan-introducing Season 6 finale. Negrete will be showrunner of the new series.

It will have some significant differences from the other shows. Unlike the other two series, which do 16-episode seasons, Season 1 of the new series will be 10 episodes. It will shoot in Virginia, which is not a place the other two have filmed. The Walking Dead is set in Virginia as of Season 9, but films in Georgia, while Fear the Walking Dead has filmed in numerous locations and is currently set and filmed in Texas.

Three young people have joined the cast. According to Variety, Alexa Mansour, Nicolas Cantu, and Hal Cumpston have been cast in major roles. Mansour, who has appeared on Madam Secretary, SEAL Team, and The Resident, will play what sounds like one of the two protagonists, who Variety sources describe as "a good-natured rule breaker who lives for today. She is likable and funny on the outside but sad on the inside." She confirmed the casting on social media. Cantu and Cumpston will play boys who are small for his age and big for his age, respectively. The other lead female role has yet to be cast.

It's coming in 2020. Production will start this summer. The first movie of the Rick Grimes TV movie trilogy is also expected next year.
