"They just have very different approaches when it comes to media attention," one insider said. "Ben hates all attention and it makes him very uncomfortable. Jennifer has always had a different approach."

Per the new movie’s synopsis, Lopez plays Atlas Shepherd, “a brilliant but misanthropic data analyst with a deep distrust of artificial intelligence.” After joining a “mission to capture a renegade robot with whom she shares a mysterious past,” her “only hope of saving the future of humanity from AI is to trust it.”

Directed by Brad Peyton from a script by Leo Sardarian and Aron Eli Coleite, Atlas also stars Simu Liu, Sterling K. Brown, Gregory James Cohan, Abraham Popoola, Lana Parrilla and Mark Strong.

In a behind-the-scenes video from the movie, which Lopez also co-produced, she opened up about why its story resonated on such a deep level.

“The first time I read the script for Atlas, I felt very passionately about the story and particularly the friendship story at the core of it,” she said in the clip, shared exclusively with PEOPLE on May 14. “At the end of it I was literally sobbing.” 

On its surface, Lopez added, “It's kind of a big action movie, but it has at the emotional core a story about love and friendship.”

Atlas is on Netflix May 24.
