How Ben Affleck Helped Wife Jennifer Lopez for Her Role in “Atlas”

The Netflix film is now available to stream on Netflix

Jennifer Lopez's Atlas costar is revealing how her husband, Ben Affleck, helped her prepare for her role.

In the new Netflix film, Lopez, 54, stars as data analyst Atlas Shepherd, whose deep distrust of artificial intelligence is tested after going on a mission to capture a renegade robot, according to a description for the Netflix film.

Her costar, Sterling K. Brown, explained why Affleck, 51, would read the lines of Smith, her AI companion, voiced by Gregory James Cohan, to help Lopez nail down her character.

"Every once in a while, Ben would read the lines for Smith. And I think the newlyweds, still very much in love, I think she just wanted to hear his voice," Brown, 48, said in an interview with Entertainment Weekly published on Friday, May 24. "And so sometimes, the reactions that you got from her were because she was listening to her husband's voice."

According to a character summary shared by Tudum, Smith is only present as a voice inside Atlas' suit.

"As the film proceeds, the initially combative duo learn to work with each other, in spite of Atlas’ many reservations," the summary adds.

It's no surprise that Lopez wanted to practice her lines with a familiar voice, as director Brad Peyton told Tudum, "The heart of Atlas is really about trust and how difficult it is to trust people."

"Atlas is told through the lens of a woman who’s learning to trust after undergoing a trauma that’s upended her life. It’s a reminder of how we have to have deep, meaningful relationships in our lives, in one way, shape, or form," said Payton. "That you can’t do everything by yourself; you have to choose to trust people at a certain point and let them in.”

Like Lopez, Affleck has also been busy working on a movie project, The Accountant 2, which caused him to miss out on attending Lopez's film premiere in Los Angeles on Monday, May 20.

His absence at the premiere also comes amid reports that the couple is living separately and are experiencing tension in their marriage.

Lopez was asked about her marriage to Affleck while promoting Atlas in Mexico City on Wednesday, May 22, causing her to tell a reporter, "You know better than that."

Simu Liu, another one of her costars, also stood to her defense, telling the reporter, "C'mon, don't come in with that energy, please.

"If I could just end on one thing, Jen is a producer on this movie, and the reason why I am here and why Sterling [K. Brown] was in this beautiful movie is because Jen cares," continued Liu, 35. "And Jen cares about things like representation and diversity, and she's a boss."
