Kidman also told the BBC Radio 2 show: “We were in lockdown; we were in Tennessee in Nashville and the director [Susanne Bier] sent me a text going, 'Would you sing the title track, "Dream a Little Dream," for the series?', I was like, 'What? No, I so don't want to do that, my voice is not good,’ which is always my reaction, and she said, 'No, no, I think you can sing it.’”

What Is the Plot of The Undoing?
Based on the Jean Hanff Korelitz novel You Should Have Known, the six-part series sees Kidman take on the role of renowned therapist Grace Fraser.
But just as Fraser is on the verge of publishing her first book, her doting husband, John, mysteriously vanishes.
A violent death and chain of devastating revelations soon leave Grace "in the wake of a spreading and very public disaster", the official synopsis reads.
In order to move on, she has no choice but to create a whole new life for herself and their son.
"I had this idea of a perfect life that I got from you and mum," Kidman's character says in the trailer. "That's really all I wanted."
