Gregory James Cohan Wasn't Supposed to Voice Smith

While Cohan voiced Smith for Atlas from the time production began, the original plan was for him to be replaced in post.

In talking with ComicBookMovie.com, director Brad Peyton revealed Gregory initially joined the cast as "a day player" and just to talk "to her during the scenes:"

"So, Greg came on to the movie as literally like a day player, like just a person who shows up, gets in the booth and just talks to her during the scenes. However, because he sounded the way I pictured him, I just treated Greg, like another member of the cast."

As time went on, the Netflix director realized audiences were "gonna fall in love with this voice:"

"I talked about Smith's arc, I talked about how he communicates with her in terms of this scene versus the middle of the movie versus the end of the movie, and by about halfway through the production, I realized, as soon as everybody sees this movie cut together, they're gonna fall in love with this voice, because everybody would come up and be like, he's great, where did you find him?"

Peyton went on to explain how there was no need to replace Cohan because he was "pitch-perfect in the role" and, like Smith, was there "just to help Atlas."

He also shared that the "movie benefits in a big way, because he [Cohan] was there for the whole ride, he was there from minute one."

While Cohan was reportedly "pitch-perfect" as Smith, his voice was not the only one Jennifer Lopez heard during filming.

In talking with Entertainment Weekly about Atlas, actor Sterling K. Brown revealed that Ben Affleck, Lopez's husband, would occasionally "read the lines for Smith:"

"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. And so sometimes, the reactions that you got from her were because she was listening to her husband's voice."
