More than a year after the sequel was announced, “The Incredibles 2” is finally chugging along.

Writer-director Brad Bird, who was also behind Pixar’s “Ratatouille,” told NPR that the sequel is “percolating.”

“I’m just staring to write it, so we’ll see what happens,” he said.

Disney CEO Bob Iger told investors at the company’s shareholders meeting in March of 2014 that Pixar was planning a sequel to “The Incredibles,” as well as a third installment of its “Cars” franchise. “The Incredibles” was released in late 2004 and went on to gross $631.4 million worldwide.

Bird also provided the voice of costume designer Edna Mode in the toon. “I was exceedingly cheap and available,” he told NPR about the experience.

He most recently directed Disney’s George Clooney-starrer “Tomorrowland,” which hits theaters on May 22.
