UPDATE with Season 6 trailer shown in Hall H: As it has in past Comic-Con appearances, AMC’s blockbuster zombie apocalypse series used its packed Hall H presentation today to drop its season-debut date. Season 6 of The Walking Dead will premiere on October 11 with a 90-minute episode, the thousands in the huge San Diego Convention Center room were told. The news came just before a trailer teasing the upcoming season – another TWD Hall H tradition. – and oh yeah, they are live debuting the new season at Madison Square Garden. (See the trailer above.) The new season will premiere internationally in a 125 countries with 24 hours of its Stateside debut, EP Gale Anne Hurd told fans.

Also like in past years, there was a big turnout from the cast and creatives of the show, with Hurd and showrunner Scott Gimple plus fellow EPs Dave Alpert and Greg Nicotero onstage. Andrew Lincoln and Norman Reedus were joined by fellow cast members Steven Yeun, Danai Gurira, Melissa McBride, Chandler Riggs, Sonequa Martin-Green, Michael Cudlitz and Lennie James. Lauren Cohan wasn’t there but sent a text telling everyone how much she missed them that Yeun read out. Fellow EP and creator of The Walking Dead comics Robert Kirkman was expected to attend as well but canceled his entire SDCC schedule this week because of throat surgery he underwent earlier this month.

The trailer showed Rick Grimes in charge of the sanctuary of Alexandria and then Lennie James’ Morgan taking over. And of course hundreds of zombies die, it looks like Norman Reedus’ Daryl Dixon gets covered in new blood and mud far away from his fellow survivors and Grace & Frankie star Ethan Embry has joined the show. “Things night not be as they seem,” teased Gimple about what the trailer really reveals about Season 6. The entire cast came out in Robert Kirkman T-shirts as Gimple announced that TWD S6 premiere would be happening in the NYC arena and fans can will tickets. Gimple also said that the upcoming season would see a lot of flashbacks, including a whole episode. With the debut of spinoff Fear The Walking Dead starting later this year, this could be a hint of some crossover.

The Season 5 debut of Walking Dead on October 12 last year set a record for the show with 17.3 million total viewers, with 11 million among adults 18-49. Another new high was hit when that debut saw double-digit rises in Live+3 DVR numbers. The Walking Dead also scored several TV touchdowns last year as it beat the NFL’s Sunday Night Football on NBC several times when the two heavyweights went head-to-head.
