Season 8 of The Walking Dead has been wild. With All Out War against The Saviors officially raging, every episode has brought a ton of shootouts and a fair amount of twist and turns. With so many fans eager to get a glimpse of what is next for the survivors and their communities, security for The Walking Dead has to be extra tight in order to prevent spoilers from being revealed. And much like popular properties like Game of Thrones and the Marvel Cinematic Universe, TWD is apparently keeping its scripts under lock and key. According to Savior actor Callan McAuliffe, it's quite the process to have access to the pages.
They send your bits of the script via an application that you have your own password on. I've never read a full script, only ever my bits... they give me [just] enough that contextually I can make something of the character.
Now that is some hardcore security. It looks like the guest actors and day players of The Walking Dead aren't privy to most of each episode's script, and might not even be aware of which direction the series is going at any given time. With a ton of communities and a large ensemble cast at play, this likely allows these cast members to still enjoy the show in real time with the fans.
Callan McAuliffe's comments to Daily Mail really highlights how rabid the Walking Dead fanbase has become, as well as the scope of the entire series. While the first few seasons of The Walking Dead had capsulated plot lines about survival, the series has transformed into an epic and expansive world, while remaining mostly loyal to Robert Kirkman's graphic novels. And with the millions of fans who tune in every Sunday to watch how things play out, there are droves of fans who would like a sneak peek into future episode's contents. As such, production has had to take some drastic measures to keep its cards close to its chest, including not giving actors access to much of the scripts.
Then again, this does make sense for the scenes were Callan McAuliffe is present. He plays a new character Alden, who is a member of Negan's many forces of Saviors. He was introduced when the satellite outpost was taken by the allied communities, and is one of the many hostages Maggie has control of in The Hilltop. There are a ton of background actors involved in these scenes, and they're relatively contained to the conflict with Maggie, Jesus, and Gregory. As such, McAuliffe and others don't need to be privy to what's going on over at The Kingdom, or how Eugene is handling things with The Saviors.
