The Emmy winner had sent the internet into overdrive after telling CNN that he would "never say never", with regards to a return for Walter.

"I think it was on the Ashley Banfield show on CNN, and she brought up the speculation," he said in a new interview with the Daily Beast. "I was just toying with her and said, "I don't know!" which created a whole brushfire of rumor."

"I don't think that we're going to see any kind of rebirth of that show, or that character," he added.

"I don't know in what context it would work in, because we're in different phases," he explained. "The characters didn't meet until the second season of Breaking Bad, when Walter needed to meet him. I suppose they could have a serendipitous brush of each other down the street or in the market, but I don't know what good that'll do-it's just a little cookie."

However, Bryan Cranston did confirm that he will be directing an episode of Better Call Saul, saying, "I'm looking forward to going down there next year and directing an episode, though. It's family. They've got the same crew, and it's exciting to think that we can rekindle that flame; that it's still alive."
