And during an October 204 conversation at Fortune’s Most Powerful Women Summit, Diaz shed some light on one of the main reasons she was returning to film: her husband’s support.

“He’s just the best,” the actress said of Benji, per E! News, continuing of her hiatus, “We were in the house for a long time, which was amazing.”

Benji, Diaz said, “was like, ‘You’ve been supporting us and building the family.’ And supporting him in his businesses. He’s like, ‘It’s time for us to support you and let Mommy ascend and do her thing.’ ”

Taking a step back from her screen career “felt like the right thing for me to reclaim my own life, and I just really didn’t care about anything else,” said Diaz: “Nobody’s opinion, nobody’s success, no one’s offer, no one’s anything could change my mind about my decision of taking care of myself and building the life that I really wanted to have.”

She added, “It really comes to what are you passionate about? For me it was to build my family.”

Back in Action is now streaming on Netflix.
