Liev Schreiber Jokes Nicole Kidman Is 'So Quick to Be Inappropriate on a Set': 'Some of the Biggest Doozies'

"One day, they will release the outtakes from this show ... and you'll see some extraordinary Nicole Kidman footage," he joked of his 'Perfect Couple' costar

Nicole Kidman has a side that fans might be surprised about, according to Liev Schreiber.

"I got things from Nicole Kidman that I had no idea existed," Schreiber, 56, admitted of his Perfect Couple costar this week on SiriusXM's The Jess Cagle Show with Julia Cunningham.

The actor explained that Kidman, 57, "really exudes grace and elegance and authority and all these things," joking in addition, "I'm here to tell you that I have never met anyone so quick to be inappropriate on a set than Nicole."

"She was just coming up with some of the biggest doozies," Schreiber went on. "One day, they will release the outtakes from this show and all of our improvs, preferably one day after we're all dead, and you'll see some extraordinary Nicole Kidman footage. It was really fun."

Schreiber told hosts Jess Cagle and Julia Cunningham that even though he and Kidman have "been friends for years," he'd "never really imagined us working together" before The Perfect Couple.

"I didn't think it would happen, so it was one of the great surprises of doing this gig and finding out about it," added the actor.

Based on New York Times bestselling author Elin Hilderbrand's novel of the same name, The Perfect Couple transports viewers to Nantucket, Massachusetts, where the Winburys are hosting a lavish family wedding at their seaside estate, Summerland.

Things take a dark turn when a body washes up on the property just hours before the bride and groom are to say, "I do." Suddenly, the quintessential family is swept up in a murder investigation — and everyone is a suspect.

Aside from Kidman and Schreiber, the cast includes Dakota Fanning, Eve Hewson, Sam Nivola, Billy Howle, Meghann Fahy, Jack Reynor, Ishaan Khatter, Mia Isaac, Michael Beach, Donna Lynne Champlin and Isabelle Adjani.
