Atlas , a new Jennifer Lopez sci-fi fest that began streaming on Netflix today, is all about artificial intelligence. There’s the bad AI robots like Simu Liu, who attack humans and plan world domination. And then there are the good, helpful AI robots—like the AI named “Smith,” who will ultimately help Lopez save the world.

Atlas —directed by Brad Peyton, with a script by Leo Sardarian and Aron Eli Coleite—stars Lopez as Atlas Shepherd, a prickly data analyst who doesn’t trust artificial intelligence. She has a good reason: Evil AI robots have waged war on humanity. Through a series of unfortunate events, Atlas ends up stranded on an alien planet, trapped in a robot suit that is powered by a “good” AI named Smith.

At first, Atlas is very mistrustful of Smith, and refuses to do the “neural link” that would allow human and machine to work seamlessly together. But when she ends up in a tight spot, she agrees to let Smith inside of her mind, and vice versa. Thus begins a beautiful friendship between a sassy human and a sassy robot.

But while we definitely know who JLo is, the voice behind her mechanical friend is a mystery. Read on to learn more about the actor who voices Smith in Atlas. Smith the AI bot from Atlas is voiced by Gregory James Cohan.

Cohan hasn’t had many lead roles in big projects, but he’s been steadily working as an actor in Hollywood for over a decade, with small guest roles on TV shows like American Horror Stories and Snowfall , as wel.
