Dark Matter, which premieres today on Apple TV+, is based on the critically acclaimed blockbuster novel of the same name by bestselling author Blake Crouch. Dark Matter follows Jason Dessen (Joel Edgerton), a physicist who is abducted while walking home and brought into an alternate universe where everything is different, including the fact that in this new world, he is not married to his wife, Daniela (Jennifer Connelly). Dessen must find his way through a labyrinth of other realities to make his way back to his own and save his family from a frightening foe: himself.

Recently, Connelly spoke with SciFi Vision about working on the thrilling sci-fi series.

In the series, although not as many as Edgerton, Connelly does play multiple versions of her character that she had to differentiate, but unlike some of his, they were “pretty separated in the episodes” and there were “pretty big distinctions” according to the actress. However, there were some things that remained the same. “I thought about that there were some fundamental characteristics of the person that I thought would remain consistent through the different versions, but that, clearly, there were ways in which the different experiences had marked her,” Connelly explained to the site. “So, I thought about that, especially in creating, Daniela Two and making choices for her, you know, most notably, she was single, she didn't have children, she was working as a visual artist and was successful in doing that. She hadn't experienced the kind of grief and loss that Daniela One had experienced. So, those were some really big differences between their lives that I think impacted the way she kind of moved through the world and interacted with people.”

Although the series centers around multiple realities and the road not taken, working on it didn’t really bring up feelings of what might have been. “To be honest, and it might sound hokey, but I'm pretty aware of how lucky I am to be where I am in my job, when I go to work every day,” said Connelly. “I am so grateful for the opportunity to do what I do. I think it's a great job and really fulfilling and I feel really fortunate to have those opportunities.”

“I feel the same about being able to spend time with my family,” she added. “I think they're just great people, my husband and my kids, and every day, I'm so grateful to be able to spend my days with them.”
