Speaking to The AV Club, the director explained that the show's network AMC had not imposed too many restrictions.
"We have not pulled any punches that we didn't want to pull anyway," he said. "I always say that sometimes in a moment of violence, sometimes less is more. In the case of a zombie thing, though, sometimes more is more, you know, so you make those creative decisions.
"What's wonderful is that when we decide more is more, we're not bumping against, 'No, we can't possibly air that!' So it's the creative choices that are leading how we portray things, not some Standards and Practices mandating limitations.
"I couldn't be happier. I know everyone's so nervous about it. 'Oh, you're doing a zombie show. I hope you get to show some blood'. Oh yeah, there'll be some blood there for you. No worries."
Darabont also claimed that The Walking Dead would never have survived as a network show, saying: "If I was doing this for one of the big three... I can't even begin to imagine the restrictions and restraints and conversations we'd be having. I would not have even gotten through the first day of shooting, I'm sure."
The Walking Dead premieres on Sunday at 10/9c on AMC in the US and on November 5 at 10pm on FX in the UK.
