Oscar Isaac’s Siblings: Facts about Nicole Hernandez Hammer & Mike Hernandez

Oscar Isaac's siblings, Nicole Hernandez Hammer and Mike Hernandez are both stars in their own right. Despite having their own lives, they remain connected and supportive of each other.

Oscar Isaac is widely recognized for his versatility as an actor, partaking in many action-packed films, among others. In 2022, he made his Marvel Cinematic Universe debut in the movie "Moon Knight," where he plays a man with dissociative identity.

Isaac comes from a family of talented people. Although in a different field, his sister is also successful as a scientist and advocate. Meanwhile, his brother is a journalist and actor who once joined him on the big screen.

Nicole Hernandez Hammer

Guatemala-born Nicole Hernandez Hammer was only four years old when her family relocated to the US. She joined the academe and was a sea-level researcher and biologist. Hammer was previously the assistant director of the Florida Center for Environmental Studies at Florida Atlantic University.

Her passion for the environment eventually made her an environmental justice advocate. She became the Union of Concerned Scientists's Florida Coastal Expert in 2012 and the Southeast Climate Science and Community Advocate.

Hammer focused much on addressing the impacts of climate change in colored low-income communities, teaching residents about the realities of climate change and the many ways they can minimize their impact on it.

In 2015, former First Lady Michelle Obama asked Hammer to join the State of the Union Address as a special guest. At that time, Hammer was a doting wife and proud mom to one son. The following year, she spoke about rising sea levels and climate change at the Democratic National Convention.

Despite being a public figure and advocate and appearing in public events for climate change, Hammer enjoys keeping her personal life private. She has an Instagram account but only allows friends and family access to her posts.

Mike Hernandez

Mike Hernandez is Isaac's younger brother and also a creative talent. He is a journalist and worked for the Miami New Times, writing an article about his childhood with Isaac in Miami. Although not yet as well-known in the industry, Hernandez is also an actor like his brother.

He supported Oscar Isaac's career and agreed to be Isaac's double in "Moon Knight." Given his dissociative disorder role, Hernandez would portray whichever character Isaac wasn't momentarily playing. Hernandez received notes and guidance from his brother throughout the project. Isaac said:

"It was wild to have him on set and to play off of. He's a great actor, and we share DNA, so he was very helpful. I couldn't have done this with anyone else. [...] He really knows me so well, so we improvise sometimes together."

Isaac contacted his brother two months before taping began and invited him to be the double. "Once he sent me that text, that was so exciting," Hernandez said. "I was just so stoked to join."

Hammer, Hernandez, and Isaac were born to Maria Eugenia and Oscar Gonzalo Hernández-Cano, of Guatemalan and Cuban descent. They relocated to the US shortly after Isaac was born and have since found success in the country. Sadly, their mother suffered from health issues and passed away in 2017.

Isaac is now a family man with two children, Eugene and Mads Isaac, whom he shares with his loving wife, Elvira Lind. The duo prefers keeping their family life away from the spotlight.
