Sunday’s season premiere of AMC’s “Breaking Bad” will mark yet another journey into this show’s heart of darkness.

I interviewed series star Bryan Cranston — he of the three consecutive Emmys for his work on “Breaking Bad” — for a cover story that’s running this Sunday in The Post’s TV Week section.

That story looks ahead to Season 4, with Cranston sharing his thoughts on the future of the show and many other topics related to his on-screen character, Walter White. Be sure to check it out.

Cranston, meanwhile, also talked about the Season 3 finale, which left “Breaking Bad” fans with a cliffhanger: did Jesse (Aaron Paul) pull the trigger and kill Walt’s lab assistant, Gale (David Costabile) — or did he flinch at the last second and miss his target (whether intentionally or not)?

(Note: I’m not about to ruin anything, so don’t worry.)

“That was a very lucky accident,” Cranston said. “What happened was . . . they wanted to move the camera so the [gun’s] muzzle was right in front of the lens, and when you move a camera and you are so focused on that object that you can’t see the background and can’t see how everything else is relative to that . . . it created this whole buzz . . . and what a very fortunate accident on our part to have that happen and create this chatter.”

Cranston also talked about Walter’s wife, Skyler (Anna Gunn) — and how, near the end of Season 3, she knowingly became involved in the criminal activity of her husband .

(Walter is a high school chemistry teacher, diagnosed with terminal lung cancer, who’s been secretly cooking pure crystal meth under his street name, “Heisenberg,” in order to leave his wife and two kids financially secure when he’s gone.)

“There’s complicity between them,” Cranston said of Walter and Skyler. “You know what’s interesting? What our show raises is that hypothetical question that I think everyone has played at some dinner party at some point or another — what would you do if you only had two years to live with your life? What would you do if you had a million dollars?

“As long as it stays in the hypothetical, I think people are able to take that high moral ground,” he said.

“But if it’s really, truly presented to you as it is with Walter and Skyler, morality becomes more ambiguous. Then it’s, ‘I don’t know. I know I’m dying here, here’s an opportunity to make a million dollars and just jump in, don’t ask too many questions.”

And Cranston, who first came to prominence on TV with his co-starring role on “Malcolm in the Middle,” knows that it’s highly unusual to have two successful series — on opposite ends of the spectrum, no less.

“When you think about it, an actor getting a successful series, by itself, is remarkable, you know?” he said. “To have two? Unheard-of.

“It’s like being struck by lightning twice.”
