Nicole Kidman, Zac Efron Share Original NSFW Title of New Romcom (Exclusive) [Video]

Nicole Kidman and Zac Efron‘s new Netflix romantic comedy was not always called A Family Affair.

“Originally, it had a different title,” Kidman, 57, reveals, while the pair spoke with PEOPLE about their new movie. “It was called Motherf—–,” Efron, 36, explains. “Beeped out,” Kidman adds. “Somehow that didn’t make it onto the Netflix title.”

Still, the arresting title made an impact as the two initially considered the project. “That made the script stay at the top of the pile,” Efron says. “It’s like, what on Earth could this be about?”

A Family Affair reunites Kidman and Efron 12 years after they first appeared together on the big screen in the chilling 2012 drama The Paperboy, in which they also played lovers. This time, Efron portrays a self-absorbed movie star who falls for the writer mother (Kidman) of his personal assistant (Joey King).
