Antonio Banderas tells PEOPLE that he and Nicole Kidman helped each other 'feel safe' while acting together in the erotic thriller 'Babygirl.' 'She was totally committed to what she was doing,' Banderas says of Kidman's leading role.

Nicole Kidman is acting within the acting – faking the Big O. She plays Romy Mathis, and when she “finishes” with hubby Jacob (Antonio Banderas), she skitters down the hall to sprawl on the floor with some porn and actually get the job done.

Antonio Banderas says Nicole Kidman made him "feel safe" on the set of 'Babygirl' and he hopes she felt that way too.

A24’s provocative drama “Babygirl” has surpassed $50 million at the global box office, with international markets delivering $22.6 million and domestic earnings reaching $27.4 million, per numbers provided by the studio.

There was the neo-noir thriller Love Lies Bleeding, the mega-viral love-triangle drama Challengers, the sex-worker-centered Cinderella story Anora, and finally — just hitting theaters with a week left in the year — Nicole Kidman and A24's Babygirl.

Babygirl has been billed as an erotic thriller: the erotic part is accurate, but it’s hardly a thriller. All up, it’s a much more ambitious movie than expected.
