Brad Pitt: Angelina Jolie Wants to Expand BRCA1 Testing (Video)
The "World War Z" star told "GMA" the couple was "surprised and moved" by the response to his partner's announcement about her double mastectomy.
Just days before he hits movie theaters as a zombie-fighting dad, Brad Pitt talked about protecting his real-life family.
"That's the only thing that keeps me up at night [as a dad]: Is everyone safe?" the World War Z star told Good Morning America.
Pitt's longtime partner, Angelina Jolie, recently took a dramatic step to guard herself against breast cancer, undergoing a preventative double mastectomy after she tested positive for a mutation of the BRCA1 gene.
Pitt said Jolie's goal now "is to make sure that all people have access to the testing and know what they can do about it."
"If you do the research and do what's best for you, it doesn't have to be a scary thing, it can be an empowering thing," Pitt added.
Pitt also shared his reaction to the response to Jolie's news, saying, "We were really surprised and moved by how many people were dealing with the same issue."
"It seems to be a galvanizing moment for people dealing with this," he noted.
Pitt also indicated that his sons may have inspired him to work on World War Z, saying that they love those kinds of projects.
The zombie apocalypse thriller, co-starring The Killing's Mireille Enos, had its release date delayed by six months due to production issues.
World War Z opens in the U.S. on Friday.
