According to The Hollywood Reporter, Gale Ann Hurd explained that the series allowed audiences to forget about their own problems.
"Given the fears in the world today, a zombie apocalypse series was less scary than, say, the financial meltdown or a disease outbreak," she said. "And zombies can be fun!"
She added: "I think the idea of the undead exists across cultures and all these problems are on everyone's minds. The show essentially examines how humans will survive such a disaster and what is the right thing for humans to do in such a situation."
Hurd, who suggested that there will be some twists in the second season, also revealed that she wants the show to continue for years.
"[Robert Kirkman, who writes the comic book series] and we hope it's 'the series that never ends'," she said.
Production for second season of The Walking Dead is expected to begin this spring.
