(CNN) Not to undo your hopes of another season "Big Little Lies," but the truth is, it's going to be a hard thing to pull off, according to Nicole Kidman.

At the Television Critics Association press tour on Wednesday, the producer and actress, who stars in a new limited series for HBO called "The Undoing," said schedules may prevent the ensemble from the Emmy-winning limited series "Big Little Lies" from getting back together any time soon. (CNN, like HBO, is owned by WarnerMedia.)

"We would love to, but... I don't think we'd ever get Laura back," Kidman said, referring to actress and cast member Laura Dern. "She's working on so many different things right now."

She's not wrong. In addition to Kidman and recent Golden Globe winner Dern , the main actresses at the helm of the series have busy careers.

Reese Witherspoon will soon appear in Hulu's "Little Fires Everywhere," Zoë Kravitz is in training for her role as the iconic Catwoman, and Shailene Woodley has a busy film slate that includes Fernando Coimbra's " Girl Named Sue ."
