Game Of Thrones' George R.R. Martin Shares The Walking Dead Survival Tip

A Game of Thrones author George R.R. Martin recently went through a 14-hour The Walking Dead binge-watching session to get caught up on the series. Over the course of his viewing, Martin came up with a simple solution to dealing with post-apocalyptic predators.

"Castles!" Martin tells EW. "Whatever is happening in the United States during The Walking Dead, I'm sure they're a lot better off in England because they're in castles. If they had any brains, they'd go to the existing castles and reinforced the walls. They can patrol on the bullwarks. No way is a zombie [getting through]—medieval seige armies couldn't break castles with conventional artillery, and zombies don't use artillery. Zombies don't build trebuchets. They don't build siege towers. There is no way they can break into a well-defended castle."

Of course, there are other complications: food, hostile fellow survivors, etc. Castle's do at least take care of the shelter and security problem better than most other structures could.

The Walking Dead airs Sundays at 9 p.m. ET on AMC.

Game of Thrones Season 5 premieres April 12 on HBO.
