Ashley Zukerman as Charlie Isaacs and Rachel Brosnahan as Abby Isaacs make up just one of the married couples in Los Alamos whose relationship is tested by the classified nature of the mission at hand.
Charlie becomes as adept in deception as he is in advanced mathematical equations.
“I think that’s exactly the tragedy of Charlie and Abby,” says Zukerman. “That, how could a couple succeed in this environment? A couple who are both strong-headed and as equal as each other — how could this work when I find out I’m working on the most horrific thing that human beings have ever invented and I can’t come home and tell my wife about it?”
“And I know that I’m begin kept in the dark,” Brosnahan adds.
“You can’t tell the secret and so things get further and further apart and as we start leading more individual lives we start changing without each other in a way,” explains Brosnahan. “And how can you come back together and understand one another when you’ve been changing independently?”
