Michael Douglas told Catherine Zeta-Jones she is "most terrifying" when she does nothing at all.
The actress has asked her husband for advice as she prepared to shoot new Netflix crime drama 'Cocaine Godmother', and she was a little taken aback by her man's words of wisdom.
Speaking on SiriusXM, she said: "As I was leaving for the airport to go shoot, [my husband] said, 'Just think of one thing. I'm gonna give you one thing to think about, darling'.
"And he said, 'You don't need to do much.' And I went, 'What do you mean? This is probably the most multi-layered, multi-faceted character I've ever ... what do you mean I haven't got to do much?'
"He went, 'No you don't have to do much because you are at your most terrifying when you do absolutely nothing.' "
Thankfully, Catherine saw the funny side - and teased her man that he must have lived in fear for almost two decades of marriage.
She laughed: "I went, 'Wow, really, after 19 years, I just do nothing and I scare the bejeezus out of you. OK, good to know.'"
The 48-year-old actress - who has been married to the 73-year-old Hollywood star for nearly 18 years - has hit out at the allegations he had behaved inappropriately towards a female employee over 30 years ago, including touching himself in front of her, saying it was "very, very upsetting".
She said: "It was very, very upsetting. Anything like that, that is erroneous and false, would take anyone by surprise."
Catherine - who has children Dylan, 17, and 14-year-old Carys with Michael - also blasted the claims as a "non-story" and is "glad" he released a statement to deny them before they were made in public.
She is quoted by the Daily Mirror newspaper as saying: "I'm glad that the non-story was put straight. It was a looming accusation and I am very happy that Michael did a pre-emptive move.
"This was something that supposedly happened 30-odd years ago and was unfounded, so Michael needed to make that stance."
